The Night the Internet Was Born | A SleepWise Story

1
00:00:00,120 --> 00:00:06,200
Tonight we drift back to a
quieter world before screens

2
00:00:06,200 --> 00:00:09,960
glowed and messages crossed
oceans.

3
00:00:10,320 --> 00:00:14,640
In an instant.
The room around you is dim,

4
00:00:15,280 --> 00:00:20,000
peaceful, the faint hum of your
own devices softened by

5
00:00:20,000 --> 00:00:25,880
distance, and as you settled
deeper into your pillow, we

6
00:00:25,880 --> 00:00:30,960
turned the clock gently
backwards, toward a time when

7
00:00:30,960 --> 00:00:37,800
communication moved slowly, like
a letter carried by a ship for

8
00:00:37,800 --> 00:00:40,440
centuries.
If you wanted to speak to

9
00:00:40,440 --> 00:00:45,320
someone far away, you needed
paper, ink, and patience.

10
00:00:45,800 --> 00:00:51,320
Messages crossed mountains by
horseback and oceans by creaking

11
00:00:51,320 --> 00:00:55,760
wooden hulls, taking weeks or
months to arrive.

12
00:00:56,640 --> 00:01:01,840
Even when they did, they could
be lost, misunderstood or

13
00:01:01,840 --> 00:01:04,920
arrived too late to change
anything at all.

14
00:01:05,239 --> 00:01:09,240
Merchants waited for news of
prices in distant ports,

15
00:01:09,720 --> 00:01:14,800
families waited for letters from
travellers, and leaders waited

16
00:01:14,800 --> 00:01:20,480
for reports from their envoys.
To live with distance was to

17
00:01:20,480 --> 00:01:24,560
live with delay.
You learned to send messages

18
00:01:24,600 --> 00:01:29,840
early, to choose words
carefully, and to accept that by

19
00:01:29,840 --> 00:01:34,640
the time a reply returned, the
world might already have

20
00:01:34,640 --> 00:01:39,520
changed.
Then, in the 9th century, thin

21
00:01:39,520 --> 00:01:44,080
wires began to Criss cross
continents, and the Telegraph

22
00:01:44,080 --> 00:01:48,680
arrived carrying dots and dashes
of Morse code.

23
00:01:49,440 --> 00:01:53,840
For the first time, a message
could leap across land in

24
00:01:53,840 --> 00:01:59,640
minutes instead of days.
The world felt smaller, but it

25
00:01:59,640 --> 00:02:03,280
was still fragile and slow
compared to what would come.

26
00:02:03,720 --> 00:02:08,919
Telephones followed, giving
voice to distance, but each call

27
00:02:08,919 --> 00:02:13,440
tied one line directly to
another, like placing a single

28
00:02:13,440 --> 00:02:17,760
board across a stream.
Networks grew.

29
00:02:18,320 --> 00:02:23,520
Cables stretched under oceans.
Switchboards clicked through the

30
00:02:23,520 --> 00:02:28,040
night, and yet everything
remained tied to circuits that

31
00:02:28,040 --> 00:02:33,560
opened and closed, connecting
and disconnecting with each call

32
00:02:33,880 --> 00:02:39,280
as you breathe slowly now, the
world we are drifting toward is

33
00:02:39,280 --> 00:02:45,040
still years away from anything
called the Internet, but the

34
00:02:45,040 --> 00:02:50,680
need that would create it is
already there, the need to share

35
00:02:50,680 --> 00:02:56,240
information quickly, reliably,
and in ways that would not break

36
00:02:56,520 --> 00:03:00,640
when one wire snapped or one
building went dark.

37
00:03:01,080 --> 00:03:06,280
The idea of a new kind of
network, more flexible, more

38
00:03:06,280 --> 00:03:12,640
patient, more resilient, is
beginning to form quietly, in

39
00:03:12,640 --> 00:03:16,280
minds that most people will
never meet.

40
00:03:16,640 --> 00:03:20,720
In the late evenings of that
earlier age, you might have

41
00:03:20,720 --> 00:03:25,440
heard the soft hiss of a radio
as it swept past distant

42
00:03:25,440 --> 00:03:30,640
stations, voices and music
skipping across the atmosphere,

43
00:03:31,200 --> 00:03:34,080
fading in and out with the
weather.

44
00:03:35,120 --> 00:03:40,000
Broadcasts could reach many
listeners at once, but they

45
00:03:40,000 --> 00:03:45,640
flowed in only One Direction,
from a single tower to countless

46
00:03:45,640 --> 00:03:48,960
ears.
If you wanted to answer back,

47
00:03:49,200 --> 00:03:53,800
you still needed pen and paper
or a planned telephone call.

48
00:03:54,160 --> 00:03:59,600
So tonight, as your own room
grows quieter and your breathing

49
00:03:59,600 --> 00:04:02,960
settles into a gentle rhythm, we
pause.

50
00:04:02,960 --> 00:04:08,480
Here, at the edge of that world,
the tools for instant two way

51
00:04:08,480 --> 00:04:14,080
communication do not exist yet,
but the longing for them does.

52
00:04:14,800 --> 00:04:19,640
A quiet question beneath the
clatter of typewriters and the

53
00:04:19,640 --> 00:04:24,520
crackle of radio.
Surely there must be a faster

54
00:04:24,520 --> 00:04:31,040
way for information to travel, A
way that does not tire, does not

55
00:04:31,040 --> 00:04:35,840
forget and does not mind how far
it has to go.

56
00:04:36,120 --> 00:04:41,160
Far beneath the noise of the
20th century wars, radio

57
00:04:41,160 --> 00:04:46,880
broadcasts, new highways and jet
engines, another quieter

58
00:04:46,880 --> 00:04:52,200
revolution was preparing itself
In laboratories and secretive

59
00:04:52,200 --> 00:04:55,120
offices.
People were learning how to make

60
00:04:55,120 --> 00:04:58,920
machines that could follow
instructions written as numbers.

61
00:05:00,000 --> 00:05:04,080
Early computers were huge,
filling entire rooms with

62
00:05:04,080 --> 00:05:08,000
cabinets, cables and spinning
reels of tape.

63
00:05:08,760 --> 00:05:12,040
They were loud and
temperamental, but they could

64
00:05:12,040 --> 00:05:16,880
perform calculations that would
take humans days or weeks,

65
00:05:17,360 --> 00:05:20,200
finishing them in minutes or
seconds.

66
00:05:20,520 --> 00:05:24,520
During the Second World War,
these machines helped decode

67
00:05:24,520 --> 00:05:28,800
encrypted messages and calculate
trajectories for artillery.

68
00:05:29,560 --> 00:05:36,160
Later, in the 1950s and 1960s,
they were used for scientific

69
00:05:36,160 --> 00:05:40,880
research, business accounting
and government record keeping.

70
00:05:41,880 --> 00:05:47,720
Still, each computer lived
mostly alone, like an island of

71
00:05:47,720 --> 00:05:53,240
logic surrounded by a sea of
paper and filing cabinets.

72
00:05:53,560 --> 00:05:56,880
If you wanted to move
information from one machine to

73
00:05:56,880 --> 00:06:01,840
another, you might carry a stack
of punch cards across a hallway

74
00:06:02,440 --> 00:06:05,560
or ship magnetic tapes across
the country.

75
00:06:06,600 --> 00:06:10,280
There was no simple way for
computers to talk to each other

76
00:06:10,280 --> 00:06:15,520
directly, no shared language for
communication, no standard roads

77
00:06:15,520 --> 00:06:19,400
between them.
At the same time the world was

78
00:06:19,400 --> 00:06:24,200
entering the long, tense years
of the Cold War, Military

79
00:06:24,200 --> 00:06:28,560
planners worried about what
would happen if a key city or

80
00:06:28,560 --> 00:06:32,360
communications hub was
destroyed.

81
00:06:33,240 --> 00:06:37,640
If all your information flowed
through a small number of

82
00:06:37,640 --> 00:06:42,240
central points, then losing
those points could be

83
00:06:42,240 --> 00:06:47,000
catastrophic.
A single failure could ripple

84
00:06:47,000 --> 00:06:50,280
outward and leave people cut
off.

85
00:06:50,600 --> 00:06:55,120
So in the background, 2 needs
began to overlap.

86
00:06:55,920 --> 00:07:01,360
On one side, scientists and
engineers wanted computers to

87
00:07:01,360 --> 00:07:05,640
share data more easily, to send
files and messages

88
00:07:05,960 --> 00:07:09,680
electronically instead of
through trucks, planes, and

89
00:07:09,680 --> 00:07:13,840
envelopes.
On the other side, strategists

90
00:07:13,920 --> 00:07:18,640
wanted a communication system
that could survive damage, one

91
00:07:18,640 --> 00:07:22,640
that would root around broken
pieces instead of collapsing.

92
00:07:23,040 --> 00:07:28,920
Tonight, as you rest, we drift
closer to the moment when those

93
00:07:28,920 --> 00:07:35,160
needs begin to meet in quiet
offices filled with hums and

94
00:07:35,160 --> 00:07:39,320
clicks.
A new ideas forming, an idea

95
00:07:39,320 --> 00:07:43,560
that will change not only how
computers talk to each other,

96
00:07:44,000 --> 00:07:48,120
but eventually how people talk
to one another as well.

97
00:07:48,440 --> 00:07:53,960
Imagine for a moment a single
long road connecting 2 cities.

98
00:07:54,920 --> 00:07:59,000
If that road is blocked, the
journey stops.

99
00:08:00,040 --> 00:08:04,520
This is how most communication
systems once worked.

100
00:08:05,440 --> 00:08:11,960
Direct, simple and fragile.
Now imagine a web of small

101
00:08:11,960 --> 00:08:17,880
streets, alleys and side paths.
If one route is closed, you

102
00:08:17,880 --> 00:08:23,000
simply take another.
The journey may change, but it

103
00:08:23,000 --> 00:08:27,400
continues.
This image of many possible

104
00:08:27,400 --> 00:08:32,880
paths instead of just one became
the seed of a new way of

105
00:08:32,880 --> 00:08:38,200
thinking about communication.
In the 1960s, researchers in

106
00:08:38,200 --> 00:08:43,320
different countries began to
imagine breaking messages into

107
00:08:43,320 --> 00:08:48,360
tiny pieces that could travel
independently across a shared

108
00:08:48,360 --> 00:08:51,480
network.
Rather than setting up a

109
00:08:51,480 --> 00:08:55,960
dedicated line for each
conversation, the network would

110
00:08:55,960 --> 00:09:01,920
carry many small chunks of data
packets intermixed each with its

111
00:09:01,920 --> 00:09:06,040
own address, like envelopes in a
crowded mailbag.

112
00:09:06,480 --> 00:09:11,560
An engineer named Paul Baron in
the United States wrote about

113
00:09:11,800 --> 00:09:16,600
distributed resilient networks,
where information would

114
00:09:16,600 --> 00:09:21,000
automatically seek alternate
routes if some nodes were

115
00:09:21,000 --> 00:09:25,240
destroyed.
In the United Kingdom, Donald

116
00:09:25,240 --> 00:09:31,360
Davies explored similar concepts
and used the word packet to

117
00:09:31,360 --> 00:09:37,360
describe these units of data.
Others in universities and

118
00:09:37,360 --> 00:09:43,160
research agencies refined these
ideas and explored how to make

119
00:09:43,160 --> 00:09:48,840
them work in real systems.
The basic principle was elegant.

120
00:09:49,320 --> 00:09:54,080
Instead of 1 fragile path, many
flexible ones.

121
00:09:54,760 --> 00:10:00,480
Instead of a single continuous
stream, countless small pieces.

122
00:10:01,280 --> 00:10:06,920
Instead of a central, easily
broken structure, a distributed

123
00:10:06,920 --> 00:10:09,840
net that could bend without
breaking.

124
00:10:10,200 --> 00:10:15,080
For ordinary people at the time,
nothing about daily life seemed

125
00:10:15,080 --> 00:10:19,120
different.
Phones still connected one call

126
00:10:19,120 --> 00:10:23,200
at a time.
Televisions still used analog

127
00:10:23,200 --> 00:10:27,080
signals.
Newspapers still arrived each

128
00:10:27,120 --> 00:10:30,280
morning.
There were no headlines about

129
00:10:30,280 --> 00:10:35,560
packet switching, no evening
broadcasts about distributed

130
00:10:35,560 --> 00:10:39,360
networks.
But beneath the surface, in

131
00:10:39,360 --> 00:10:44,200
technical journals and quiet
conferences, the blueprint of a

132
00:10:44,200 --> 00:10:47,040
new kind of network was taking
shape.

133
00:10:47,840 --> 00:10:53,120
It did not yet have a familiar
name, but its outline was clear,

134
00:10:53,800 --> 00:10:58,080
a system that would move
information with calm

135
00:10:58,080 --> 00:11:04,720
persistence, even when parts of
it were damaged or overloaded to

136
00:11:04,760 --> 00:11:08,000
night.
We keep following this thread

137
00:11:08,320 --> 00:11:13,920
from idea to experiment, and
from experiment to the first

138
00:11:13,920 --> 00:11:19,000
small pieces of a network that
would someday circle the globe.

139
00:11:19,480 --> 00:11:25,000
To turn theory into reality,
someone had to build a working

140
00:11:25,000 --> 00:11:28,600
network, not just describe one
on paper.

141
00:11:28,960 --> 00:11:34,880
In the United States, a research
agency called ARPA, the Advanced

142
00:11:34,880 --> 00:11:39,000
Research Projects Agency, took
on this challenge.

143
00:11:39,920 --> 00:11:45,640
ARPA funded cutting edge work in
computing and communications,

144
00:11:46,040 --> 00:11:50,160
bringing together universities
and laboratories that were

145
00:11:50,160 --> 00:11:53,200
exploring the frontiers of
technology.

146
00:11:53,600 --> 00:11:58,520
The goal was simple in words,
but complicated in practice.

147
00:11:59,200 --> 00:12:03,920
Connect their computers so they
could share data, programs and

148
00:12:04,080 --> 00:12:08,440
expensive resources. 4 sites
were chosen for the first

149
00:12:08,440 --> 00:12:12,480
version of this experimental
network, which would be called

150
00:12:12,840 --> 00:12:17,120
ARPANET.
One was at UCLA in California,

151
00:12:17,320 --> 00:12:23,200
another at the Stanford Research
Institute nearby, 1/3 was at UC

152
00:12:23,200 --> 00:12:28,560
Santa Barbara, and a fourth at
the University of Utah.

153
00:12:29,480 --> 00:12:34,800
Each location had a different
type of computer and its own

154
00:12:34,880 --> 00:12:39,560
operating system.
To connect them, engineers

155
00:12:39,560 --> 00:12:45,000
designed special interface
machines, small, rugged

156
00:12:45,000 --> 00:12:50,120
computers dedicated to carrying
data between the local computer

157
00:12:50,600 --> 00:12:55,040
and the network.
These were called IM PS:

158
00:12:55,320 --> 00:13:02,760
Interface message processors.
Each IMP would act like a local

159
00:13:02,760 --> 00:13:07,960
post office, receiving messages,
splitting them into packets if

160
00:13:07,960 --> 00:13:12,720
needed, and forwarding them
along leased telephone lines to

161
00:13:12,720 --> 00:13:18,040
other IM PS.
In 1969, the first links of

162
00:13:18,120 --> 00:13:23,560
ARPANET came to life.
At first, the network was tiny,

163
00:13:24,160 --> 00:13:29,280
just a handful of sites sending
simple messages at speeds that

164
00:13:29,280 --> 00:13:32,320
today would feel incredibly
slow.

165
00:13:33,240 --> 00:13:36,880
The rooms that housed the
equipment were unremarkable.

166
00:13:37,000 --> 00:13:40,720
Racks of hardware, cables,
humming fans, paper logs on

167
00:13:40,720 --> 00:13:44,160
clipboards.
Yet within those rooms,

168
00:13:44,640 --> 00:13:49,800
something new was happening.
Messages were no longer confined

169
00:13:49,800 --> 00:13:54,440
to a single machine.
A program at UCLA could send

170
00:13:54,440 --> 00:13:59,080
data to a computer in Utah.
A researcher at Stanford could

171
00:13:59,080 --> 00:14:02,000
access resources stored in Santa
Barbara.

172
00:14:02,960 --> 00:14:07,280
Distance, at least for these
machines, was beginning to

173
00:14:07,280 --> 00:14:11,120
matter less.
Few people outside these circles

174
00:14:11,320 --> 00:14:14,920
paid attention.
The world had other headlines,

175
00:14:15,160 --> 00:14:20,680
other worries, but for the small
group building ARPANET, each

176
00:14:20,680 --> 00:14:26,680
successful transmission was a
quiet sign that this new way of

177
00:14:26,680 --> 00:14:30,080
moving information could
actually work.

178
00:14:30,400 --> 00:14:36,480
As you lie here now, surrounded
by your own devices, you are

179
00:14:36,480 --> 00:14:41,000
living with the mature version
of an idea that started with

180
00:14:41,000 --> 00:14:46,360
these modest links, these
careful experiments, these late

181
00:14:46,360 --> 00:14:50,840
nights in fluorescent lit labs
where the future of

182
00:14:50,840 --> 00:14:54,160
communication first blinked into
being.

183
00:14:54,720 --> 00:14:58,640
There is a small, almost
accidental moment in the history

184
00:14:58,640 --> 00:15:03,840
of the Internet that people
still remember, and it begins

185
00:15:04,360 --> 00:15:11,920
with a simple word Logan.
On an October evening in 1969,

186
00:15:12,440 --> 00:15:18,280
researchers at UCLA attempted to
connect to a computer at the

187
00:15:18,280 --> 00:15:24,360
Stanford Research Institute over
one of the first ARPANET links.

188
00:15:24,720 --> 00:15:29,280
Their plan was to log in
remotely, something we now do

189
00:15:29,280 --> 00:15:33,760
without thinking.
But at the time it was new and

190
00:15:33,760 --> 00:15:36,800
delicate.
Sitting at their terminal, they

191
00:15:36,800 --> 00:15:40,800
typed the 1st letter L.
They checked with their

192
00:15:40,800 --> 00:15:45,360
colleagues at Stanford.
We see the L.

193
00:15:45,840 --> 00:15:49,320
Came the confirmation.
Then they typed the next letter

194
00:15:49,680 --> 00:15:52,880
O.
Again the signal travelled and

195
00:15:52,880 --> 00:15:56,720
again Stanford responded.
We see the O.

196
00:15:57,080 --> 00:16:01,680
The moment they tried to type
the 3rd letter G, the system

197
00:16:01,880 --> 00:16:05,760
crashed.
The connection dropped and their

198
00:16:05,760 --> 00:16:13,240
message, which was supposed to
read Logan, was cut off at LO. 2

199
00:16:13,240 --> 00:16:16,640
letters, a tiny fragment of a
word.

200
00:16:17,000 --> 00:16:22,720
Yet in that small failure, a
quiet success was hiding.

201
00:16:23,640 --> 00:16:28,840
A message had travelled from one
computer through the ARPANET to

202
00:16:28,840 --> 00:16:32,400
another computer hundreds of
kilometers away.

203
00:16:33,120 --> 00:16:35,880
The link worked, even if only
briefly.

204
00:16:36,720 --> 00:16:41,600
Data had flowed across a network
instead of being carried in a

205
00:16:41,600 --> 00:16:46,080
box or on paper.
The next day, they tried again,

206
00:16:46,680 --> 00:16:51,360
and the log in succeeded.
There were no journalists

207
00:16:51,360 --> 00:16:56,200
watching, no crowds cheering.
Just a handful of tired

208
00:16:56,200 --> 00:17:01,400
researchers watching texts
appear on a distant screen and

209
00:17:01,400 --> 00:17:05,160
realizing that something
important had changed.

210
00:17:05,560 --> 00:17:10,520
Tonight, as your own messages
travel invisibly across

211
00:17:10,520 --> 00:17:14,839
continents in fractions of a
second, you're living in the

212
00:17:14,839 --> 00:17:22,640
Long Echo of that LO the first
faint syllable of a connection

213
00:17:22,880 --> 00:17:27,680
that would eventually encompass
millions of machines and then

214
00:17:27,680 --> 00:17:31,480
billions of people.
What began with two letters has

215
00:17:31,480 --> 00:17:34,920
grown into an entire digital
universe.

216
00:17:35,240 --> 00:17:40,560
Once the basic connections were
in place, ARPANET began to grow,

217
00:17:40,920 --> 00:17:46,640
and with growth came new habits,
new tools, and new ways of using

218
00:17:46,640 --> 00:17:51,320
a network that had started as a
technical experiment.

219
00:17:51,720 --> 00:17:56,440
One of the most important
developments was surprisingly

220
00:17:56,440 --> 00:18:02,120
human a way to send messages
from one person to another, not

221
00:18:02,120 --> 00:18:04,360
just from one computer to
another.

222
00:18:04,680 --> 00:18:12,080
In the early 1970s, a programmer
named Ray Tomlinson experimented

223
00:18:12,080 --> 00:18:17,400
with software that could deliver
electronic mail between users on

224
00:18:17,400 --> 00:18:21,280
different machines connected to
ARPANET.

225
00:18:21,760 --> 00:18:24,880
To distinguish between the
person and the computer they

226
00:18:24,880 --> 00:18:29,880
used, he chose a symbol that was
rarely used in names.

227
00:18:30,600 --> 00:18:37,960
The a a sign a message might go
to user a machine indicating

228
00:18:37,960 --> 00:18:41,960
both the individual and the host
where they could be reached.

229
00:18:42,840 --> 00:18:48,040
It was a small detail, but it
gave shape to something new.

230
00:18:48,680 --> 00:18:52,680
e-mail.
As we now recognize it, e-mail

231
00:18:52,680 --> 00:18:55,240
spread quickly among network
users.

232
00:18:55,680 --> 00:19:00,520
It became a natural way to share
updates, coordinate projects,

233
00:19:01,040 --> 00:19:06,400
and send short notes.
Mailing lists emerged, allowing

234
00:19:06,400 --> 00:19:10,880
groups of people to discuss
topics together, their messages

235
00:19:11,000 --> 00:19:16,800
threaded through shared inboxes
in these text only exchanges.

236
00:19:17,440 --> 00:19:22,760
Early online communities were
forming long before social media

237
00:19:23,040 --> 00:19:27,360
and instant messaging.
What had begun as a tool for

238
00:19:27,360 --> 00:19:32,920
sharing computing resources was
slowly becoming a social space.

239
00:19:33,720 --> 00:19:38,360
People sent jokes, holiday
wishes and informal comments

240
00:19:38,680 --> 00:19:43,000
alongside research papers and
technical questions.

241
00:19:44,040 --> 00:19:48,000
The network was no longer just
about machines talking to

242
00:19:48,000 --> 00:19:50,960
machines.
It was about people talking to

243
00:19:50,960 --> 00:19:56,480
one another through machines.
Still, ARPANET remained a small

244
00:19:56,480 --> 00:20:00,720
world, mostly limited to
researchers, students and

245
00:20:00,720 --> 00:20:04,760
government workers.
The general public was largely

246
00:20:04,800 --> 00:20:09,240
unaware that any of this
existed, but the pattern was

247
00:20:09,240 --> 00:20:13,480
clear.
Build a network for one purpose,

248
00:20:14,040 --> 00:20:17,840
and humans will fill it with
their own voices, their own

249
00:20:17,840 --> 00:20:20,560
stories, their own sense of
connection.

250
00:20:20,920 --> 00:20:26,040
As you breathe gently, you can
picture those early terminals

251
00:20:26,040 --> 00:20:32,200
glowing in dim offices late at
night as someone reads a new

252
00:20:32,200 --> 00:20:38,960
e-mail, a few lines of text
arriving from far away, proving

253
00:20:38,960 --> 00:20:44,000
that a network of computers can
also be a network of human

254
00:20:44,000 --> 00:20:48,280
beings.
As ARPANET expanded, it met a

255
00:20:48,280 --> 00:20:52,640
new challenge.
It was not the only network

256
00:20:52,640 --> 00:20:55,440
anymore.
Other computer networks were

257
00:20:55,440 --> 00:20:59,760
beginning to appear academic
systems in different countries,

258
00:21:00,080 --> 00:21:05,320
specialized networks for certain
research communities, and later

259
00:21:05,680 --> 00:21:08,480
networks run by private
companies.

260
00:21:09,240 --> 00:21:14,560
Many of them use their own
protocols, their own rules for

261
00:21:14,560 --> 00:21:17,040
formatting and transmitting
data.

262
00:21:17,400 --> 00:21:22,000
If each network remained
separate, the world would end up

263
00:21:22,000 --> 00:21:25,600
with many isolated islands of
connectivity.

264
00:21:26,600 --> 00:21:31,360
You might be able to talk easily
within one island, but jumping

265
00:21:31,360 --> 00:21:36,240
from one to another would be
difficult or impossible.

266
00:21:37,000 --> 00:21:41,440
That was not the vision forming
in the minds of some engineers

267
00:21:41,440 --> 00:21:45,680
and computer scientists.
They imagined something larger,

268
00:21:46,560 --> 00:21:51,920
a network of networks, a way for
different systems to connect

269
00:21:51,920 --> 00:21:55,400
while still keeping their
internal designs.

270
00:21:56,160 --> 00:22:01,680
For that to work, they needed a
shared set of rules that all

271
00:22:01,680 --> 00:22:05,760
networks could agree to when
talking to each other.

272
00:22:06,160 --> 00:22:11,880
Two researchers, Vint Cerf and
Bob Kahn, worked on this

273
00:22:11,880 --> 00:22:15,240
problem.
They developed a family of

274
00:22:15,240 --> 00:22:19,440
protocols that would allow
diverse networks to send data

275
00:22:19,440 --> 00:22:23,720
between them reliably.
Their design focused on

276
00:22:23,720 --> 00:22:28,040
splitting information into
packets, giving each packet,

277
00:22:28,240 --> 00:22:34,200
addressing details, and handling
lost or reordered packets in a

278
00:22:34,200 --> 00:22:39,720
systematic way.
They called this family TCPIP,

279
00:22:40,040 --> 00:22:44,800
Transmission Control Protocol
and Internet Protocol.

280
00:22:45,600 --> 00:22:50,760
TCP would ensure that data
arrived correctly and in the

281
00:22:50,760 --> 00:22:56,280
right order.
IP would define how packets were

282
00:22:56,280 --> 00:23:00,320
addressed and routed from one
network to another.

283
00:23:00,680 --> 00:23:04,880
The beauty of this approach was
its flexibility.

284
00:23:05,720 --> 00:23:12,880
TCP IP did not require any
specific type of underlying

285
00:23:12,880 --> 00:23:17,000
network.
It could run over phone lines,

286
00:23:17,400 --> 00:23:23,280
satellite links, radio
connections, or fiber optic

287
00:23:23,280 --> 00:23:26,320
cables.
It did not ask everyone to

288
00:23:26,320 --> 00:23:28,680
rebuild their systems from
scratch.

289
00:23:29,080 --> 00:23:33,480
It simply offered a common
language for them to use when

290
00:23:33,480 --> 00:23:36,680
they need it to interconnect.
Tonight.

291
00:23:37,040 --> 00:23:44,120
Those 4 letters TCP IP might
sound distant and technical, but

292
00:23:44,120 --> 00:23:47,920
they quietly shape almost
everything you do online.

293
00:23:48,320 --> 00:23:51,960
They are like grammar and
punctuation for digital

294
00:23:51,960 --> 00:23:56,760
communication, keeping billions
of tiny messages moving in an

295
00:23:56,760 --> 00:24:01,040
orderly way even though you
rarely notice them at all.

296
00:24:01,360 --> 00:24:08,800
On January 1st, 1983, something
subtle but profound happened in

297
00:24:08,800 --> 00:24:13,560
the story of the Internet.
This date is often called Flag

298
00:24:13,560 --> 00:24:18,040
Day for the network.
It was the day when ARPANET

299
00:24:18,040 --> 00:24:23,680
officially switched from its
older protocol NCP to the newer

300
00:24:24,040 --> 00:24:30,760
TCP for IP standard.
Before this, different parts of

301
00:24:30,760 --> 00:24:34,720
the network had used different
methods to communicate.

302
00:24:35,040 --> 00:24:39,840
Afterward, TCPIP would become
the common language for

303
00:24:39,840 --> 00:24:44,600
connecting not just ARPANET, but
many other networks as well.

304
00:24:44,960 --> 00:24:48,880
The transition required careful
preparation.

305
00:24:49,880 --> 00:24:55,000
System administrators updated
configurations, installed new

306
00:24:55,000 --> 00:25:01,440
software and tested connections.
Machines had to be ready to

307
00:25:01,440 --> 00:25:07,040
speak the new protocol by a
specific time or they risk being

308
00:25:07,040 --> 00:25:10,600
left behind.
There were no fireworks, no

309
00:25:10,600 --> 00:25:15,640
crowded ceremonies, just quiet
work carried out by people who

310
00:25:15,640 --> 00:25:20,400
understood that this change
would enable the network to

311
00:25:20,400 --> 00:25:23,720
grow.
Around the same time, the

312
00:25:23,720 --> 00:25:30,240
National Science Foundation in
the United States created NNSF

313
00:25:30,240 --> 00:25:36,680
Net, a high speed backbone
network linking supercomputing

314
00:25:36,680 --> 00:25:41,320
centers and universities.
Other countries developed their

315
00:25:41,320 --> 00:25:44,240
own academic and research
networks.

316
00:25:44,560 --> 00:25:48,680
Commercial networks were
beginning to appear too, hinting

317
00:25:48,680 --> 00:25:52,280
at a future where the Internet
would not be limited to

318
00:25:52,280 --> 00:25:58,120
government and academic use.
The word Internet, short for

319
00:25:58,120 --> 00:26:03,920
Internet Work, began to be used
more widely to describe this

320
00:26:03,920 --> 00:26:07,640
growing web of interconnected
systems.

321
00:26:08,600 --> 00:26:14,040
It was still small by modern
standards and still mainly used

322
00:26:14,040 --> 00:26:18,360
by specialists, but the
architecture was in place,

323
00:26:18,600 --> 00:26:23,160
shared protocols, multiple
networks, and a culture of

324
00:26:23,160 --> 00:26:28,440
collaboration among the people
who built and maintained them.

325
00:26:28,840 --> 00:26:33,320
For most people in the early
1980s, this world remained

326
00:26:33,320 --> 00:26:36,720
invisible.
Home computers were just

327
00:26:36,720 --> 00:26:40,760
starting to spread.
Connecting to anything beyond a

328
00:26:40,760 --> 00:26:45,920
local machine often meant dial
up modems and specialized

329
00:26:45,920 --> 00:26:49,360
services, not open Internet
access.

330
00:26:49,720 --> 00:26:54,480
Yet the foundation was ready.
All that was missing was a

331
00:26:54,480 --> 00:26:58,600
simple, intuitive way for
ordinary users to move through

332
00:26:58,600 --> 00:27:05,080
this interconnected space, a way
to click, read and explore

333
00:27:05,320 --> 00:27:08,760
without needing to memorize
addresses or understand

334
00:27:08,760 --> 00:27:12,680
commands.
That next step was already

335
00:27:12,680 --> 00:27:19,200
taking shape quietly in a
physics laboratory in Europe by

336
00:27:19,200 --> 00:27:22,360
the mid 1980's.
The Internet as an

337
00:27:22,360 --> 00:27:27,520
infrastructure existed, but it
did not yet feel like a place

338
00:27:27,520 --> 00:27:32,960
where you could simply browse.
Finding information meant

339
00:27:32,960 --> 00:27:38,200
knowing exactly where to look,
which server house to file, what

340
00:27:38,200 --> 00:27:41,840
path to type, which commands to
use.

341
00:27:42,280 --> 00:27:48,440
Tools like FTP and telnet
allowed experienced users to log

342
00:27:48,440 --> 00:27:51,560
into remote systems and retrieve
data.

343
00:27:52,280 --> 00:27:56,440
But these tools were not
designed for ease or comfort.

344
00:27:57,560 --> 00:28:04,760
There was number single, unified
space of information, just many

345
00:28:04,760 --> 00:28:10,000
scattered repositories.
At CERN, a European physics

346
00:28:10,000 --> 00:28:14,680
laboratory in Switzerland,
scientists felt this problem

347
00:28:15,200 --> 00:28:19,280
every day.
They came from universities

348
00:28:19,280 --> 00:28:25,080
across the world, collaborated
on large experiments, and

349
00:28:25,080 --> 00:28:29,480
constantly needed to share
papers, diagrams and notes.

350
00:28:29,920 --> 00:28:34,760
Their information lived in
different systems, in different

351
00:28:34,760 --> 00:28:41,520
formats, often hard to find
unless you already knew exactly

352
00:28:41,520 --> 00:28:45,760
what you needed.
A British computer scientist at

353
00:28:45,760 --> 00:28:53,080
CERN, Tim Berners Lee, began to
imagine a gentler way to connect

354
00:28:53,360 --> 00:28:58,400
all this information.
He thought about hypertext

355
00:28:59,040 --> 00:29:03,520
documents that could contain
links, simple references you

356
00:29:03,520 --> 00:29:07,560
could follow from one piece of
information to another, no

357
00:29:07,560 --> 00:29:09,880
matter where the documents were
stored.

358
00:29:10,280 --> 00:29:13,760
If you could combine hypertext
with the internet's global

359
00:29:13,760 --> 00:29:18,720
reach, you might create a
universal reading room, a web of

360
00:29:18,720 --> 00:29:22,640
documents linked together,
accessible from anywhere.

361
00:29:23,040 --> 00:29:29,480
To make this work, he proposed 3
key components, URL's to

362
00:29:29,480 --> 00:29:36,480
identify resources, HTTP as a
protocol for requesting them,

363
00:29:37,160 --> 00:29:43,680
and HTML as a simple language
for structuring documents and

364
00:29:43,680 --> 00:29:48,080
embedding links.
He called the system the World

365
00:29:48,080 --> 00:29:52,000
Wide Web.
At first it was a modest

366
00:29:52,000 --> 00:29:57,240
internal project at CERN meant
to help physicists manage their

367
00:29:57,520 --> 00:30:02,720
overflowing documentation.
Berners Lee wrote the first web

368
00:30:02,720 --> 00:30:07,520
server, the first browser, and
some of the first pages himself.

369
00:30:08,280 --> 00:30:13,520
There were no images, no videos,
no ads, just text and links

370
00:30:14,040 --> 00:30:17,760
forming A sparse but powerful
network of knowledge.

371
00:30:18,200 --> 00:30:22,440
Tonight, as you lie here, you
are surrounded by the

372
00:30:22,440 --> 00:30:28,440
descendants of that experiment,
sites and pages and services

373
00:30:28,720 --> 00:30:34,200
built on the same basic idea
that any document can point to

374
00:30:34,280 --> 00:30:38,040
any other.
That knowledge can be interwoven

375
00:30:38,040 --> 00:30:42,000
into a web that stretches
quietly around the planet.

376
00:30:42,360 --> 00:30:47,840
In the beginning, the World Wide
Web was small, almost fragile.

377
00:30:48,200 --> 00:30:53,960
The early browsers were simple,
off and running in text only

378
00:30:53,960 --> 00:30:58,200
terminals.
Users navigated through lists of

379
00:30:58,200 --> 00:31:03,920
links, selecting one to move to
another document, then another,

380
00:31:04,520 --> 00:31:07,760
stepping through the web one
page at a time.

381
00:31:08,160 --> 00:31:13,400
The experience was new but still
somewhat technical, a tool

382
00:31:13,400 --> 00:31:16,120
mainly for researchers and
enthusiasts.

383
00:31:16,480 --> 00:31:22,680
Then, in the early 1990s, more
user friendly browsers began to

384
00:31:22,680 --> 00:31:26,720
appear.
One of the most influential was

385
00:31:26,720 --> 00:31:30,560
Mosaic, developed at the
National Center for

386
00:31:30,560 --> 00:31:33,920
Supercomputing Applications in
the United States.

387
00:31:34,280 --> 00:31:39,960
Mosaic could display images in
line with text, not just as

388
00:31:39,960 --> 00:31:44,240
separate files.
It ran on common personal

389
00:31:44,240 --> 00:31:49,080
computers with graphical
interfaces that felt familiar to

390
00:31:49,080 --> 00:31:54,560
people already using Windows or
Macintosh systems.

391
00:31:54,960 --> 00:31:57,360
This changed the feeling of the
Web.

392
00:31:58,080 --> 00:32:02,160
Instead of looking like a
collection of plain text files,

393
00:32:02,720 --> 00:32:08,520
it began to resemble something
more like a digital magazine or

394
00:32:08,960 --> 00:32:13,240
bulletin board.
Pages could include pictures,

395
00:32:13,360 --> 00:32:19,200
headings, and basic formatting,
inviting casual exploration.

396
00:32:19,600 --> 00:32:25,320
As Mosaic spread, new websites
appeared university home pages,

397
00:32:25,320 --> 00:32:29,640
personal projects, small
business sites, early news

398
00:32:29,640 --> 00:32:33,240
pages.
People experimented with color

399
00:32:33,360 --> 00:32:36,640
layout and simple navigation
menus.

400
00:32:37,280 --> 00:32:42,240
Soon, companies like Netscape
built on mosaics ideas,

401
00:32:42,720 --> 00:32:47,480
releasing browsers that were
faster, more polished, and

402
00:32:47,480 --> 00:32:51,280
easier to install.
The web's growth became

403
00:32:51,280 --> 00:32:54,800
exponential.
What had once been a tool for a

404
00:32:54,800 --> 00:32:59,880
narrow group of scientists
transformed into a public space

405
00:32:59,880 --> 00:33:03,280
open to anyone with a computer
and a connection.

406
00:33:04,120 --> 00:33:08,360
Directories and early search
engines tried to keep up,

407
00:33:08,520 --> 00:33:13,520
organizing and indexing A
rapidly expanding universe of

408
00:33:13,520 --> 00:33:16,720
pages behind this colorful
surface.

409
00:33:17,080 --> 00:33:19,560
The old machinery still did its
work.

410
00:33:20,280 --> 00:33:26,240
TCP IP routing packets, DNS
translating names like

411
00:33:26,520 --> 00:33:31,800
example.com into numerical
addresses, servers receiving

412
00:33:31,800 --> 00:33:36,840
requests and sending responses.
The complexity remained hidden,

413
00:33:37,280 --> 00:33:41,720
tucked away behind simple
gestures, typing an address,

414
00:33:42,160 --> 00:33:47,520
clicking a link, watching a page
appear in the soft darkness

415
00:33:47,520 --> 00:33:51,000
around you.
Now it may be hard to imagine

416
00:33:51,000 --> 00:33:55,680
how magical that first
experience of the web felt to

417
00:33:55,680 --> 00:34:00,480
many people.
The sense that with a few clicks

418
00:34:01,000 --> 00:34:06,400
you could wander from a lab in
Europe to a library in America

419
00:34:07,120 --> 00:34:12,320
to a hobbyist's page in Asia,
all without leaving your chair.

420
00:34:12,679 --> 00:34:18,520
Beneath the metaphors of webs
and clouds, the Internet has

421
00:34:18,520 --> 00:34:21,719
always depended on very physical
things.

422
00:34:22,040 --> 00:34:26,480
If you could lift the surface of
the oceans like a sheet and peer

423
00:34:26,480 --> 00:34:31,440
underneath, you would see thick
cables resting on the sea bed,

424
00:34:31,760 --> 00:34:36,360
crossing basins and ridges
connecting continents.

425
00:34:36,679 --> 00:34:43,040
Inside these submarine cables,
bundles of ultra thin glass

426
00:34:43,040 --> 00:34:49,199
fibers guide pulses of light
that carry most of the world's

427
00:34:49,199 --> 00:34:52,960
international data.
Specialized ships lay these

428
00:34:52,960 --> 00:34:58,280
cables slowly, unspooling them
across thousands of kilometers.

429
00:34:59,120 --> 00:35:04,600
Engineers plan routes carefully
to avoid undersea hazards, and

430
00:35:04,600 --> 00:35:09,520
protective layers shield the
fragile fibers from pressure and

431
00:35:09,520 --> 00:35:15,600
accidental damage along the way.
Repeaters, small amplifying

432
00:35:15,600 --> 00:35:20,280
stations, boost the signals so
the light can travel long

433
00:35:20,280 --> 00:35:26,520
distances without fading on.
Land cables rise from the sea

434
00:35:26,520 --> 00:35:31,200
into landing stations, then
spread outward along underground

435
00:35:31,200 --> 00:35:36,280
ducts and overhead lines.
They run alongside highways,

436
00:35:36,480 --> 00:35:40,760
under city streets, through
rural fields and into large

437
00:35:40,760 --> 00:35:46,720
buildings called data centers,
quiet, carefully controlled

438
00:35:46,720 --> 00:35:52,280
spaces where servers are stored.
Inside a data center, the air is

439
00:35:52,280 --> 00:35:56,960
cool and dry.
Rows of metal racks hold servers

440
00:35:56,960 --> 00:35:59,440
that blink with small indicator
lights.

441
00:36:00,160 --> 00:36:05,160
The constant hum of fans and
power supplies blends into a

442
00:36:05,160 --> 00:36:08,920
steady background noise like
distant wind.

443
00:36:09,800 --> 00:36:14,240
Power systems ensure that even
if the grid falters, the

444
00:36:14,240 --> 00:36:18,600
machines keep running.
Network switches and routers

445
00:36:18,600 --> 00:36:23,880
move data between racks, between
rooms, and out to the wider

446
00:36:23,880 --> 00:36:27,360
world.
From data centers, fiber

447
00:36:27,360 --> 00:36:31,360
continues its journey outward,
branching into residential

448
00:36:31,360 --> 00:36:35,080
neighborhoods, office towers,
schools and shops.

449
00:36:35,800 --> 00:36:42,720
Sometimes it remains as fiber,
sometimes it changes to copper

450
00:36:42,720 --> 00:36:48,760
cables or coaxial lines.
But the principle is the same, a

451
00:36:48,760 --> 00:36:54,440
path through which packets can
flow, turning physical distances

452
00:36:54,440 --> 00:36:58,680
into something that can be
crossed in milliseconds as you

453
00:36:58,680 --> 00:37:02,080
breathe slowly.
You might imagine this network

454
00:37:02,360 --> 00:37:07,240
as a kind of global nervous
system, signals racing back and

455
00:37:07,240 --> 00:37:12,480
forth between distant points.
But unlike A biological system,

456
00:37:12,800 --> 00:37:18,920
this one is built and maintained
by people, upgraded piece by

457
00:37:18,920 --> 00:37:23,800
piece, expanded whenever someone
decides to connect a new

458
00:37:23,800 --> 00:37:26,600
building, a new town, a new
shore.

459
00:37:27,000 --> 00:37:31,440
Above the cables and buried
lines, another layer of the

460
00:37:31,440 --> 00:37:34,600
Internet floats through the air
itself.

461
00:37:34,920 --> 00:37:40,480
Radio waves and microwaves carry
data across cities, over hills

462
00:37:40,760 --> 00:37:47,440
and between towers, on rooftops,
along highways and dotted across

463
00:37:47,520 --> 00:37:53,000
open fields.
Cell towers quietly listen and

464
00:37:53,000 --> 00:37:58,760
transmit, their antennas pointed
and tuned to serve the devices

465
00:37:58,760 --> 00:38:03,640
around them.
Your phone, resting nearby, is

466
00:38:03,640 --> 00:38:08,680
one of those devices.
Even when it seems still and

467
00:38:08,680 --> 00:38:14,560
silent, it may be exchanging
tiny bursts of information with

468
00:38:14,560 --> 00:38:19,360
nearby towers, checking for
messages, confirming its

469
00:38:19,360 --> 00:38:22,680
presence on the network, staying
ready.

470
00:38:23,440 --> 00:38:28,600
Wi-Fi routers tucked onto
shelves and in corners of homes

471
00:38:28,600 --> 00:38:32,280
and offices take wired
connections and share them

472
00:38:32,280 --> 00:38:38,240
wirelessly within a local space.
Their signals are invisible and

473
00:38:38,240 --> 00:38:44,000
silent, bouncing off walls and
furniture, filling rooms with

474
00:38:44,000 --> 00:38:49,400
connectivity that most people
notice only when it disappears.

475
00:38:49,640 --> 00:38:53,560
Far above.
Satellites in orbit add yet

476
00:38:53,560 --> 00:38:57,680
another layer.
Some relay high capacity links

477
00:38:58,040 --> 00:39:03,800
between distant ground stations.
Others form constellations

478
00:39:03,800 --> 00:39:08,640
designed to bring Internet
access to remote regions where

479
00:39:08,640 --> 00:39:12,640
laying cables would be difficult
or expensive.

480
00:39:13,440 --> 00:39:18,800
They receive beams of data from
Earth, process and forward them,

481
00:39:19,400 --> 00:39:23,160
and send them back down in
carefully timed patterns.

482
00:39:23,520 --> 00:39:28,880
For a user, all of this is
reduced to simple icons, a set

483
00:39:28,880 --> 00:39:33,960
of bars indicating cellular
strength, a small symbol for

484
00:39:33,960 --> 00:39:39,520
Wi-Fi, perhaps a tiny arrow
showing that data is being sent

485
00:39:39,520 --> 00:39:44,240
or received.
The complexity dissolves into

486
00:39:44,240 --> 00:39:49,520
the feeling that information is
just there.

487
00:39:49,840 --> 00:39:54,640
In reality, every message you
send rides on a chain of

488
00:39:54,640 --> 00:39:59,760
carefully coordinated signals.
Light and fiber radio in the

489
00:39:59,800 --> 00:40:03,880
air, switching decisions in
routers and base stations.

490
00:40:04,600 --> 00:40:08,240
The same basic idea persists
through all of it.

491
00:40:08,760 --> 00:40:12,800
Your data is broken into
packets, labeled with

492
00:40:12,800 --> 00:40:16,880
destinations, and handed from
one point to another.

493
00:40:17,600 --> 00:40:21,120
Until it reaches where it needs
to go.

494
00:40:21,440 --> 00:40:27,200
As you exhale, you can let those
details recede, knowing that the

495
00:40:27,200 --> 00:40:32,520
intricate dance of waves and
photons will continue on its

496
00:40:32,520 --> 00:40:38,520
own, quietly, while you rest.
As the underlying network became

497
00:40:38,520 --> 00:40:43,160
more capable, the way people
used it began to shift from

498
00:40:43,360 --> 00:40:49,320
occasional visits to something
closer to continuous presence.

499
00:40:49,600 --> 00:40:53,840
In the early days of home
access, most users connected

500
00:40:53,840 --> 00:40:57,880
through dial up modems to go
online.

501
00:40:58,280 --> 00:41:03,920
You would pick up the phone
line, dial A number, and listen

502
00:41:04,280 --> 00:41:10,440
as the modem translated digital
data into patterns of sound,

503
00:41:11,160 --> 00:41:17,880
chirps, hisses and static.
Being online was a distinct

504
00:41:17,880 --> 00:41:21,480
activity, something you began
and ended.

505
00:41:22,160 --> 00:41:25,280
Often.
You could not use the phone and

506
00:41:25,280 --> 00:41:30,760
the Internet at the same time.
With the spread of broadband

507
00:41:30,760 --> 00:41:37,000
connections, cable, DSL, and
later fiber, the idea of the

508
00:41:37,000 --> 00:41:41,760
Internet changed.
It stopped being a place you

509
00:41:41,760 --> 00:41:46,400
went for a short period and
became more like a utility,

510
00:41:47,040 --> 00:41:49,320
always available in the
background.

511
00:41:49,640 --> 00:41:54,120
Your computer could stay
connected all day, quietly

512
00:41:54,120 --> 00:41:59,720
syncing e-mail, downloading
updates, and loading pages

513
00:42:00,080 --> 00:42:02,800
without lengthy dialing
routines.

514
00:42:03,200 --> 00:42:08,240
Websites evolved as well.
Instead of static pages updated

515
00:42:08,240 --> 00:42:11,360
rarely.
They became dynamic and

516
00:42:11,360 --> 00:42:14,880
interactive.
Scripts running in browsers and

517
00:42:14,880 --> 00:42:19,960
on servers allowed content to
change based on who was visiting

518
00:42:20,360 --> 00:42:24,160
and what they were doing.
Pages could remember

519
00:42:24,160 --> 00:42:28,920
preferences, display live
information, and respond

520
00:42:29,040 --> 00:42:34,120
instantly to user actions.
Databases and server side

521
00:42:34,120 --> 00:42:38,400
applications turned websites
into full-fledged services,

522
00:42:38,960 --> 00:42:45,440
online stores, banking portals,
media libraries and

523
00:42:45,440 --> 00:42:49,680
collaboration platforms.
Search engines grew more

524
00:42:49,680 --> 00:42:56,040
powerful, indexing billions of
pages so that a few typed words

525
00:42:56,040 --> 00:43:01,560
could retrieve information from
almost anywhere in the world.

526
00:43:01,960 --> 00:43:07,280
Social spaces emerged where
people could post updates, share

527
00:43:07,280 --> 00:43:11,280
photos, and connect with friends
and strangers.

528
00:43:12,280 --> 00:43:15,960
The web was number longer, just
a collection of documents.

529
00:43:16,400 --> 00:43:20,840
It had become a living
environment of applications and

530
00:43:20,840 --> 00:43:24,480
communities.
Through all this, the same

531
00:43:24,480 --> 00:43:28,800
humble mechanisms continued to
work behind the scenes.

532
00:43:29,360 --> 00:43:34,760
Packets, protocols, cables and
routers scaling up to handle

533
00:43:34,760 --> 00:43:39,800
more traffic, more users and
more complexity.

534
00:43:40,120 --> 00:43:44,920
Tonight, as you lie quietly in
your room, the connection around

535
00:43:44,920 --> 00:43:50,280
you feels effortless.
It is easy to forget how recent

536
00:43:50,280 --> 00:43:55,600
this always on world really is
and how carefully its

537
00:43:55,600 --> 00:44:01,240
foundations were laid. 1
protocol and one cable at a

538
00:44:01,240 --> 00:44:05,040
time.
The arrival of smartphones made

539
00:44:05,040 --> 00:44:10,120
the Internet feel less like a
destination and more like a

540
00:44:10,560 --> 00:44:14,480
layer wrapped around everyday
life.

541
00:44:14,800 --> 00:44:18,960
Early mobile phones could handle
simple text messages and brief

542
00:44:18,960 --> 00:44:23,400
calls, but their data
capabilities were limited.

543
00:44:24,040 --> 00:44:29,280
Screens were small, connections
were slow, and browsing was

544
00:44:29,320 --> 00:44:33,160
awkward.
Yet even then, the promise was

545
00:44:33,160 --> 00:44:37,600
visible, the idea that the
network could follow you instead

546
00:44:37,600 --> 00:44:43,120
of waiting for you at a desk.
Overtime, wireless standards

547
00:44:43,120 --> 00:44:47,520
improved.
Third generation 3G networks

548
00:44:47,520 --> 00:44:52,000
brought better speeds.
Then 4G made streaming and rich

549
00:44:52,000 --> 00:44:56,800
media practical on the go.
Phone screens became brighter

550
00:44:56,800 --> 00:45:02,320
and sharper, touch interfaces
more fluid and processors more

551
00:45:02,320 --> 00:45:06,240
powerful.
The modern smartphone emerged a

552
00:45:06,240 --> 00:45:10,920
small handheld computer that
also happened to make calls.

553
00:45:11,280 --> 00:45:16,200
With that change, the Internet
moved into pockets and bags.

554
00:45:16,760 --> 00:45:19,440
Maps could draw routes in real
time.

555
00:45:20,040 --> 00:45:24,640
Messages could be sent from
trains, parks and cafe tables.

556
00:45:25,280 --> 00:45:31,120
News, music and videos could be
accessed while standing in line

557
00:45:31,320 --> 00:45:36,840
or riding in a taxi.
The boundary between online and

558
00:45:36,880 --> 00:45:42,440
offline blurred even further.
Apps appeared for almost every

559
00:45:42,440 --> 00:45:46,760
purpose, chatting, working,
exercising, meditating,

560
00:45:46,760 --> 00:45:50,400
learning, ordering food, hailing
rides.

561
00:45:51,280 --> 00:45:56,400
Location services allowed phones
to know roughly where they were,

562
00:45:56,840 --> 00:46:02,320
enabling turn by turn directions
and nearby recommendations.

563
00:46:03,200 --> 00:46:08,000
Cameras always connected, turned
into portals for sharing

564
00:46:08,000 --> 00:46:12,640
moments, instantly letting
people broadcast pieces of their

565
00:46:12,640 --> 00:46:15,640
lives to friends or to the
world.

566
00:46:15,920 --> 00:46:20,360
For the network itself, this
meant accommodating far more

567
00:46:20,360 --> 00:46:26,120
connections, each moving between
cell towers as users walked and

568
00:46:26,120 --> 00:46:32,360
travelled. 5th generation 5G
technologies pushed speeds

569
00:46:32,360 --> 00:46:37,080
higher and delays lower,
preparing for a future with not

570
00:46:37,080 --> 00:46:41,240
just phones and computers
online, but also sensors,

571
00:46:41,480 --> 00:46:48,320
vehicles and everyday objects.
And yet, even at this scale, the

572
00:46:48,320 --> 00:46:52,600
same core idea continued to
guide everything.

573
00:46:53,400 --> 00:46:59,080
Packets traveling between
devices and servers routed over

574
00:46:59,080 --> 00:47:03,480
shared infrastructure, all
following rules that had been

575
00:47:03,480 --> 00:47:09,440
defined decades earlier.
Now, as your own phone rests

576
00:47:09,440 --> 00:47:16,280
nearby, it is a quiet doorway
into this vast, constantly

577
00:47:16,280 --> 00:47:21,360
shifting environment.
You can choose for this moment

578
00:47:21,920 --> 00:47:27,200
to leave that door closed,
letting the notifications wait

579
00:47:27,800 --> 00:47:30,520
while you drift further into
calm.

580
00:47:30,960 --> 00:47:35,880
With the network always at hand,
new forms of community emerged

581
00:47:36,320 --> 00:47:40,720
not only in neighborhoods and
workplaces, but among people who

582
00:47:40,720 --> 00:47:43,720
might never share the same
physical space.

583
00:47:44,080 --> 00:47:47,720
Early online communities formed
around mailing lists and

584
00:47:47,720 --> 00:47:52,520
bulletin boards, where text
posts were organized into

585
00:47:52,520 --> 00:47:57,320
threads.
Later, forums, blogs, and social

586
00:47:57,320 --> 00:48:02,040
networks created more structured
spaces for conversation and

587
00:48:02,040 --> 00:48:06,000
sharing.
Each platform became a kind of

588
00:48:06,320 --> 00:48:11,200
digital town square, shaped by
its design and its culture.

589
00:48:11,600 --> 00:48:15,440
People gathered around hobbies,
professions, languages, and

590
00:48:15,440 --> 00:48:19,280
experiences.
Programmers helped each other

591
00:48:19,280 --> 00:48:24,040
solve problems.
Artists shared their work and

592
00:48:24,040 --> 00:48:29,840
asked for feedback.
Fans of books, games and films

593
00:48:30,200 --> 00:48:32,920
found others who loved the same
things.

594
00:48:33,520 --> 00:48:37,240
Support groups formed where
people could talk about health,

595
00:48:37,680 --> 00:48:44,680
grief or personal challenges,
often with a sense of anonymity

596
00:48:44,680 --> 00:48:50,880
that made honesty easier.
These spaces offered comfort and

597
00:48:50,880 --> 00:48:56,960
connection, especially to those
who felt isolated in their

598
00:48:56,960 --> 00:49:01,920
offline lives.
A person in one country could

599
00:49:01,920 --> 00:49:06,160
find a friend in another, united
by a shared interest or

600
00:49:06,160 --> 00:49:09,160
struggle.
Yet the same tools that made

601
00:49:09,160 --> 00:49:13,200
kindness easy also made conflict
easy.

602
00:49:14,160 --> 00:49:19,200
Disagreements could spread
rapidly, amplified by algorithms

603
00:49:19,200 --> 00:49:21,560
that rewarded attention and
engagement.

604
00:49:22,480 --> 00:49:28,120
Misinformation travelled
quickly, sometimes faster than

605
00:49:28,120 --> 00:49:31,960
careful corrections.
The line between genuine

606
00:49:31,960 --> 00:49:34,840
discussion and performance
blurred.

607
00:49:35,160 --> 00:49:41,160
Researchers and designers began
to think more deeply about how

608
00:49:41,240 --> 00:49:46,520
online environments affect mood,
behavior and discourse.

609
00:49:47,200 --> 00:49:50,960
Some platforms experimented with
features to slow down

610
00:49:50,960 --> 00:49:56,240
interactions, encourage
reflection, or reduce harmful

611
00:49:56,240 --> 00:50:00,040
content.
Others focused on giving users

612
00:50:00,040 --> 00:50:04,640
more control over what they saw.
Throughout it all, the

613
00:50:04,720 --> 00:50:08,520
underlying technology remained
neutral.

614
00:50:09,320 --> 00:50:14,480
The network did not judge the
messages it carried, it simply

615
00:50:14,480 --> 00:50:19,640
moved bits from one place to
another, faithfully delivering

616
00:50:19,640 --> 00:50:24,640
whatever people chose to send.
As you breathe gently, you can

617
00:50:24,640 --> 00:50:28,760
think of the Internet as a wide,
many sided mirror.

618
00:50:29,280 --> 00:50:35,840
It reflects curiosity and
creativity, but also fear and

619
00:50:35,840 --> 00:50:40,080
frustration.
What appears in that reflection

620
00:50:40,320 --> 00:50:45,240
depends not only on chips and
cables but on human choices,

621
00:50:45,360 --> 00:50:51,000
large and small, made every day.
Behind the visible world of

622
00:50:51,000 --> 00:50:56,920
websites and apps lies another,
quieter layer of the Internet

623
00:50:56,920 --> 00:51:01,040
story, the question of who
guides it.

624
00:51:01,360 --> 00:51:06,640
Unlike a single utility company
or centralized authority, the

625
00:51:06,680 --> 00:51:11,240
Internet is governed by a loose
constellation of organizations,

626
00:51:11,800 --> 00:51:16,160
technical groups, companies, and
governments.

627
00:51:17,080 --> 00:51:21,920
No one person can flip a switch
and change it all at once, yet

628
00:51:21,920 --> 00:51:27,240
many different entities can
influence how it grows and how

629
00:51:27,240 --> 00:51:31,000
it feels to use technical
standards.

630
00:51:31,280 --> 00:51:36,000
The detailed rules for how
protocols work are often

631
00:51:36,000 --> 00:51:38,600
developed in open working
groups.

632
00:51:39,320 --> 00:51:44,040
Engineers and experts from
around the world join mailing

633
00:51:44,040 --> 00:51:47,840
lists, meetings and drafting
sessions.

634
00:51:48,240 --> 00:51:52,160
They debate how to improve
security, how to handle

635
00:51:52,160 --> 00:51:56,920
congestion, how to support new
kinds of applications.

636
00:51:58,000 --> 00:52:04,000
The process can be slow and
careful, but its openness helps

637
00:52:04,000 --> 00:52:09,880
ensure that no single company
owns the basic building blocks.

638
00:52:10,240 --> 00:52:17,240
Domain names, the human readable
addresses like example.org, are

639
00:52:17,240 --> 00:52:22,400
coordinated through a global
system overseen by organizations

640
00:52:22,400 --> 00:52:28,000
such as ICANN.
Registries manage top level

641
00:52:28,000 --> 00:52:35,000
domains, registrars help users
register names, and name servers

642
00:52:35,120 --> 00:52:39,680
translate those names into
numerical IP addresses.

643
00:52:40,680 --> 00:52:45,640
It is a layered system built to
be robust and distributed.

644
00:52:45,960 --> 00:52:50,040
Internet service providers and
backbone operators manage the

645
00:52:50,040 --> 00:52:55,000
physical and commercial aspects
of connectivity, which routes

646
00:52:55,000 --> 00:53:00,400
data will take, how much
capacity to build, how to price

647
00:53:00,400 --> 00:53:04,360
access.
Their choices shape who can get

648
00:53:04,360 --> 00:53:08,280
online, at what speed, and at
what cost.

649
00:53:08,680 --> 00:53:12,480
Governments, meanwhile, set laws
and regulations that affect

650
00:53:12,480 --> 00:53:17,840
privacy, data protection,
censorship and competition.

651
00:53:18,760 --> 00:53:23,080
Some emphasize Open Access and
freedom of expression.

652
00:53:23,840 --> 00:53:28,640
Others impose tighter controls,
filtering or blocking certain

653
00:53:28,640 --> 00:53:33,040
content.
The result is not a single

654
00:53:33,160 --> 00:53:38,880
uniform experience, but a
patchwork of policies resting on

655
00:53:38,880 --> 00:53:43,440
shared technical foundations.
As you let your thoughts drift,

656
00:53:43,800 --> 00:53:47,560
you might imagine this
governance less as a strict

657
00:53:47,560 --> 00:53:52,440
hierarchy and more as a shifting
conversation.

658
00:53:53,000 --> 00:53:58,520
Many voices around many tables,
sometimes cooperating, sometimes

659
00:53:58,520 --> 00:54:03,680
disagreeing, all influencing the
pathways along which your data

660
00:54:04,120 --> 00:55:18,720
quietly flows.
For all its reach and

661
00:55:18,720 --> 00:55:22,960
sophistication, the Internet is
not invulnerable.

662
00:55:23,520 --> 00:55:27,880
It can falter, fragment and
fail.

663
00:55:28,160 --> 00:55:32,720
Sometimes a construction crew
accidentally cuts through a

664
00:55:32,720 --> 00:55:38,880
buried fiber optic cable and a
region loses connectivity until

665
00:55:38,880 --> 00:55:44,040
repairs are made.
At other times, misconfigured

666
00:55:44,040 --> 00:55:48,880
routing tables send data along
inefficient or broken paths,

667
00:55:49,440 --> 00:55:53,960
causing slowdowns or outages
that ripple across providers.

668
00:55:54,760 --> 00:55:59,360
Power failures in key data
centers can briefly silence

669
00:55:59,360 --> 00:56:03,880
major services.
Natural disasters, storms,

670
00:56:03,880 --> 00:56:08,840
earthquakes, floods can damage
infrastructure, taking down

671
00:56:08,840 --> 00:56:13,760
lines and equipment.
Cyber attacks can overwhelm

672
00:56:13,760 --> 00:56:18,760
servers with traffic or exploit
software vulnerabilities to

673
00:56:18,760 --> 00:56:23,560
disrupt operations.
In these moments, the Internet

674
00:56:23,560 --> 00:56:26,600
reveals its physical and human
underpinnings.

675
00:56:27,200 --> 00:56:32,720
Cables that can break, machines
that can fail, people who can

676
00:56:32,720 --> 00:56:37,040
make mistakes.
To reduce these risks, engineers

677
00:56:37,040 --> 00:56:40,240
design resilience into the
system.

678
00:56:40,920 --> 00:56:45,200
Multiple cables connect
important hubs so that traffic

679
00:56:45,200 --> 00:56:49,480
can be rerouted.
Content delivery networks cache

680
00:56:49,480 --> 00:56:54,440
data in many locations so a
video or page can be served from

681
00:56:54,440 --> 00:56:58,040
a nearby server even if another
goes down.

682
00:56:58,880 --> 00:57:03,120
Backup power and replication
help keep critical services

683
00:57:03,120 --> 00:57:06,480
available.
Monitoring systems watch traffic

684
00:57:06,480 --> 00:57:10,400
patterns and alert operators
when something seems wrong.

685
00:57:11,400 --> 00:57:16,760
Automated tools can reroute
traffic, spin up new servers, or

686
00:57:16,760 --> 00:57:20,680
block malicious activity in
response to trouble.

687
00:57:21,720 --> 00:57:27,800
After each major incident, teams
analyze what happened and adjust

688
00:57:27,800 --> 00:57:30,960
their designs to prevent similar
failures.

689
00:57:31,360 --> 00:57:36,280
Despite these efforts, moments
of fragility still occur,

690
00:57:36,880 --> 00:57:41,640
reminding us that the Internet
is not a magical substance

691
00:57:41,640 --> 00:57:46,160
floating in the air, but an
intricate, evolving

692
00:57:46,160 --> 00:57:50,480
construction.
It is strong but not

693
00:57:50,480 --> 00:57:54,880
unbreakable, flexible but not
perfect.

694
00:57:55,240 --> 00:58:00,360
As you lie here, you might take
comfort in that imperfection.

695
00:58:01,040 --> 00:58:06,640
Like a living Organism, the
network learns, adapts, and

696
00:58:06,640 --> 00:58:10,240
recovers.
It is maintained by countless

697
00:58:10,240 --> 00:58:15,360
people working behind the
scenes, many of whom you will

698
00:58:15,360 --> 00:58:20,840
never know, quietly keeping the
world's conversations flowing.

699
00:58:21,280 --> 00:58:26,960
Now, in the soft stillness of
your room, we return to the

700
00:58:26,960 --> 00:58:30,080
present.
The device you are using,

701
00:58:30,360 --> 00:58:35,400
whether it is a phone, a tablet,
or a computer, is a small

702
00:58:35,400 --> 00:58:39,400
doorway into everything we have
just traced.

703
00:58:40,240 --> 00:58:45,320
The cables on the ocean floor,
the routers and data centers,

704
00:58:45,840 --> 00:58:51,040
the antennas on rooftops, the
satellites overhead, the

705
00:58:51,040 --> 00:58:55,560
protocols and standards and
names that bind it all together.

706
00:58:55,960 --> 00:59:00,160
When you tap a link or press
play, you are calling upon

707
00:59:00,160 --> 00:59:04,760
decades of ideas and effort.
Telegraph lines and early

708
00:59:04,760 --> 00:59:09,080
computers.
Cold War concerns and research

709
00:59:09,080 --> 00:59:12,520
grants.
Academic collaborations and

710
00:59:12,520 --> 00:59:16,800
commercial ventures.
All of these threads have woven

711
00:59:16,800 --> 00:59:21,320
together into the fabric that
now feels so ordinary.

712
00:59:21,640 --> 00:59:25,520
The Internet, you know, is not
the product of a single

713
00:59:25,520 --> 00:59:31,160
breakthrough or a single mind.
It is the result of many small

714
00:59:31,160 --> 00:59:35,560
decisions.
A researcher picking the ahre

715
00:59:35,560 --> 00:59:40,520
symbol for e-mail.
An engineer defining how packets

716
00:59:40,520 --> 00:59:44,560
are acknowledged.
A ship's crew carefully laying a

717
00:59:44,560 --> 00:59:47,680
cable across a deep ocean
trench.

718
00:59:47,680 --> 00:59:52,120
A-Team at a laboratory designing
an easy to use web browser.

719
00:59:52,480 --> 00:59:56,400
Most of the people who shaped
this system worked in quiet

720
00:59:56,400 --> 01:00:02,080
offices and labs, often late at
night, surrounded by the soft

721
01:00:02,080 --> 01:00:06,160
clatter of keyboards and the
gentle whir of fans.

722
01:00:07,200 --> 01:00:10,400
They were not trying to change
the world all at once.

723
01:00:11,160 --> 01:00:16,640
They were solving specific
problems step by step, often

724
01:00:16,640 --> 01:00:20,680
unaware of how far their work
would ultimately reach.

725
01:00:21,080 --> 01:00:25,560
As you feel your body sink a
little deeper into the mattress,

726
01:00:26,240 --> 01:00:31,240
you can let the scale of this
whole story fade into the

727
01:00:31,240 --> 01:00:36,040
background.
The Internet becomes again what

728
01:00:36,040 --> 01:00:41,600
it was always meant to be,
infrastructure, a set of tools

729
01:00:41,600 --> 01:00:46,680
and pathways quietly supporting
the things you actually care

730
01:00:46,680 --> 01:00:51,280
about.
Relationships, ideas, creativity

731
01:00:51,760 --> 01:00:55,880
and rest.
For tonight, it is enough simply

732
01:00:56,080 --> 01:01:00,680
to know that this vast,
intricate system stands ready

733
01:01:00,760 --> 01:01:06,880
outside your window, humming
softly while you allow yourself

734
01:01:07,400 --> 01:01:11,720
to be still.
And so we have drifted from

735
01:01:11,720 --> 01:01:17,000
letters carried by ships to
packets moving at the speed of

736
01:01:17,000 --> 01:01:24,600
light, from isolated machines to
a planetary web, from a small

737
01:01:24,600 --> 01:01:31,240
experiment called Arpanet to an
Internet that touches billions

738
01:01:31,240 --> 01:01:35,960
of lives each day.
For all its complexity, the

739
01:01:35,960 --> 01:01:38,640
Internet remains something
deeply human.

740
01:01:39,280 --> 01:01:43,520
It carries our questions and
answers, our work and our play.

741
01:01:44,040 --> 01:01:48,520
It holds archives of knowledge
and spontaneous bursts of

742
01:01:48,520 --> 01:01:52,200
emotion.
It stores our photos, our

743
01:01:52,200 --> 01:01:58,040
messages, our songs, our
stories, every connection.

744
01:01:58,280 --> 01:02:03,720
At its heart is one person
reaching out and another person

745
01:02:03,720 --> 01:02:07,280
receiving.
Tonight you have followed this

746
01:02:07,280 --> 01:02:11,560
story not by walking down
corridors of machines or

747
01:02:11,760 --> 01:02:17,840
unspooling cables, but simply by
listening while invisible

748
01:02:17,840 --> 01:02:22,000
signals travelled between
distant servers and your own

749
01:02:22,000 --> 01:02:26,560
device.
The subject of our journey, the

750
01:02:26,560 --> 01:02:32,040
Internet itself, is also the
means by which this journey

751
01:02:32,040 --> 01:02:35,120
reached you.
As the day's thoughts grow

752
01:02:35,120 --> 01:02:39,760
softer, you can imagine screens
dimming around the world.

753
01:02:40,320 --> 01:02:43,720
Some people are just waking up
and logging on.

754
01:02:43,720 --> 01:02:47,720
Others are closing laptops and
putting phones face down.

755
01:02:48,400 --> 01:02:51,320
Routers blink steadily in quiet
rooms.

756
01:02:51,800 --> 01:02:57,040
Data centers hum under cool air.
Undersea cables continue their

757
01:02:57,080 --> 01:03:02,760
patient work.
The network does not sleep, but

758
01:03:02,760 --> 01:03:06,640
it does not rush either.
It simply waits.

759
01:03:07,000 --> 01:03:09,840
You are free to let go of it for
now.

760
01:03:10,600 --> 01:03:15,280
Notifications, messages, and
updates can all remain

761
01:03:15,280 --> 01:03:19,200
untouched.
The world will continue to move,

762
01:03:19,840 --> 01:03:25,600
Conversations will continue to
flow, but you do not need to

763
01:03:25,600 --> 01:03:30,600
keep pace with them.
Tonight, the world slows and so

764
01:03:30,600 --> 01:03:32,320
do we.
Good night.
