1 00:00:00,287 --> 00:00:04,534 So, have you ever wondered who actually invented the internet? 2 00:00:05,117 --> 00:00:08,274 Some people have become zillionaires thanks to the internet. 3 00:00:08,594 --> 00:00:11,645 But all they did was invent clever ways of using the internet. 4 00:00:12,125 --> 00:00:15,957 So the person who “invented the internet” should be a gazillionaire 5 00:00:15,957 --> 00:00:17,939 equivalent to, say, God, shoudn't they? 6 00:00:18,799 --> 00:00:20,498 Who should get the credit, then? 7 00:00:20,828 --> 00:00:23,039 Was it a British geek in a Swiss underground lab? 8 00:00:23,469 --> 00:00:24,007 Maybe. 9 00:00:24,227 --> 00:00:27,527 Clever Americans threatened with nuclear annihilation by the Russians? 10 00:00:28,087 --> 00:00:28,775 Nice idea. 11 00:00:29,385 --> 00:00:34,700 French scientists who decided to call their computer network the “Le Internet”? 12 00:00:34,980 --> 00:00:35,682 Interesting. 13 00:00:36,542 --> 00:00:39,902 Or was it thanks to a myriad of smart scientists working on something 14 00:00:39,902 --> 00:00:43,818 they knew was useful, but didn’t realize would be so big? 15 00:00:51,198 --> 00:00:53,252 Well, let’s try and get some facts straight. 16 00:00:53,661 --> 00:00:57,708 There’s the internet, a whole bunch of computer networks connected to each other, 17 00:00:57,708 --> 00:01:01,954 and then there’s the World Wide Web, a way of making it easier to share 18 00:01:01,954 --> 00:01:05,392 information using all those interconnected computers. 19 00:01:06,042 --> 00:01:10,046 The internet as we know it today was at least 40 years in the making. 20 00:01:10,716 --> 00:01:14,970 One popular but wrong story is that the internet was developed by the USA 21 00:01:14,970 --> 00:01:19,135 so they had a communication network that would survive a nuclear war. 22 00:01:19,805 --> 00:01:23,753 According to one of the founders of the first network, the ARPANET, in the 1960s, 23 00:01:23,753 --> 00:01:27,767 this first network experiment wasn’t about communication at all; 24 00:01:27,767 --> 00:01:31,362 it was about optimizing processor usage, or time-sharing, 25 00:01:31,362 --> 00:01:34,857 which basically meant that scientists could share computer power, too. 26 00:01:35,637 --> 00:01:40,283 That was because until the 1960s there was basically no network—you had big machines 27 00:01:40,283 --> 00:01:44,570 called mainframes which sat in the room and processed computing tasks 28 00:01:44,570 --> 00:01:45,456 one at a time. 29 00:01:46,176 --> 00:01:49,903 With time-sharing, these behemoths could process several tasks at a time, 30 00:01:49,903 --> 00:01:53,667 which meant their power could be used by several scientists at once. 31 00:01:54,427 --> 00:01:57,570 And, obviously, once you start connecting computers together, 32 00:01:57,570 --> 00:02:00,176 you start to wonder about what you need to do 33 00:02:00,176 --> 00:02:02,717 to make communications between them easier. 34 00:02:03,487 --> 00:02:06,530 Scientists around the world were trying to solve this problem. 35 00:02:06,990 --> 00:02:10,587 So let’s look at some other key concepts that were developed elsewhere. 36 00:02:11,427 --> 00:02:13,064 Starting with packet switching. 37 00:02:13,424 --> 00:02:16,106 In Britain, there was a commercial network, developed by the 38 00:02:16,106 --> 00:02:19,391 National Physical Laboratory, but which never really got off the ground 39 00:02:19,391 --> 00:02:20,944 because it didn’t get funding. 40 00:02:21,684 --> 00:02:25,103 But they did come up with the idea of packet switching, a way of avoiding 41 00:02:25,103 --> 00:02:28,866 congestion in busy networks by cutting up data at one end and 42 00:02:28,866 --> 00:02:30,453 putting it back together at the other. 43 00:02:31,463 --> 00:02:33,192 The French also played a role. 44 00:02:33,392 --> 00:02:36,650 They were working on a scientific network called CYCLADES, 45 00:02:36,650 --> 00:02:41,533 but they didn’t have a big budget, so they decided to work on direct connections 46 00:02:41,533 --> 00:02:45,144 between computers, as opposed to working with gateway computers. 47 00:02:45,894 --> 00:02:49,696 Now, as an aside here, this, admittedly, isn’t very scientific, 48 00:02:49,696 --> 00:02:54,820 but according to one theory, a spin-off of their research was the word “internet”. 49 00:02:55,420 --> 00:02:57,468 But you don’t have to believe it if you don’t want to. 50 00:02:58,318 --> 00:03:00,615 So, now it’s the early 1970s. 51 00:03:00,815 --> 00:03:03,680 There’s quite a lot of computer infrastructure, but communication 52 00:03:03,680 --> 00:03:07,489 is awkward and patchy, because different networks can’t talk to each other. 53 00:03:08,239 --> 00:03:10,823 TCP/IP solves this problem. 54 00:03:11,273 --> 00:03:15,585 The TCP/IP protocols form the basic communication language of the internet, 55 00:03:15,585 --> 00:03:18,336 which labels the packets of data and makes sure that 56 00:03:18,336 --> 00:03:21,329 even though some pieces of the same data take a different route, 57 00:03:21,329 --> 00:03:24,990 they all arrive at their destination and can be reassembled. 58 00:03:25,690 --> 00:03:29,500 Networks really began communicating with each other in 1975, 59 00:03:29,500 --> 00:03:32,618 so you could argue that was the beginning of the internet. 60 00:03:33,248 --> 00:03:35,185 Email was also very important. 61 00:03:35,255 --> 00:03:37,534 It was developed for ARPANET in 1972. 62 00:03:38,324 --> 00:03:42,959 Most internet traffic in 1976 was email, because academics thought 63 00:03:42,959 --> 00:03:45,252 electronic post-it notes were dead-core. 64 00:03:46,142 --> 00:03:49,965 With networks that could talk to each other, communication was becoming easier. 65 00:03:50,525 --> 00:03:55,351 But all this communication was just text- based, and it was pretty ugly to look at. 66 00:03:56,321 --> 00:03:58,931 In the 1980s, a Brit called Timothy Berners-Lee 67 00:03:58,931 --> 00:04:02,808 spent time with CERN, the European Organization for Nuclear Research, 68 00:04:02,808 --> 00:04:07,143 where physicists are trying to work out what the universe is made of. 69 00:04:07,623 --> 00:04:11,190 He wanted to manage the scientists’ information and make it possible for them 70 00:04:11,190 --> 00:04:13,346 to share and interconnect their work easily, 71 00:04:13,346 --> 00:04:15,511 making progress more likely. 72 00:04:16,301 --> 00:04:21,575 He did so by inventing an interface using HTTP, HTML, and URLs 73 00:04:21,575 --> 00:04:23,734 that made internet browsers possible. 74 00:04:24,164 --> 00:04:26,713 He called his browser the World Wide Web. 75 00:04:26,933 --> 00:04:31,390 So he didn’t invent the internet, but he did invent the Web. 76 00:04:31,950 --> 00:04:37,217 The first ever website, which he created, was at CERN in France in August 1991. 77 00:04:37,827 --> 00:04:40,290 So, once the initial infrastructure was in place, 78 00:04:40,290 --> 00:04:42,249 the key technologies had been invented, 79 00:04:42,249 --> 00:04:45,217 internet message boards exploded in the 1980s, 80 00:04:45,217 --> 00:04:48,563 the phone companies saw the commercial potential of digital communication, 81 00:04:48,563 --> 00:04:51,905 web browsers spread like wildfire in the early 1990s, 82 00:04:51,905 --> 00:04:53,734 and ordinary people discovered email, 83 00:04:53,734 --> 00:04:57,371 then the internet expanded rapidly and steadily 84 00:04:57,371 --> 00:05:01,083 and became workable for the masses from about 1995. 85 00:05:01,963 --> 00:05:05,714 Hold on, didn’t US Vice President Al Gore invent the internet? 86 00:05:06,204 --> 00:05:07,195 Ugh… no. 87 00:05:07,365 --> 00:05:11,512 And if you read what he said exactly, you’ll know he never claimed to have done. 88 00:05:11,992 --> 00:05:15,403 But many people credit him with energetically pushing legislation 89 00:05:15,403 --> 00:05:17,556 that encouraged the spread of the internet. 90 00:05:18,676 --> 00:05:21,762 The internet exists because we need to communicate, 91 00:05:21,762 --> 00:05:24,252 and most of us like doing it. 92 00:05:24,782 --> 00:05:28,123 That’s why humans have become the dominant species on Earth. 93 00:05:28,743 --> 00:05:32,538 You could argue that the internet is a natural evolutionary step 94 00:05:32,538 --> 00:05:35,581 and a manifestation of that need. 95 00:05:36,141 --> 00:05:38,672 It wasn’t invented by anyone in particular, 96 00:05:38,672 --> 00:05:42,345 but when the building blocks were put together by all those cool scientists 97 00:05:42,345 --> 00:05:45,988 from all over the place, the internet became a communication tool, 98 00:05:45,988 --> 00:05:50,526 a retail tool, a research tool, a propaganda tool, a spying tool, 99 00:05:50,526 --> 00:05:53,923 a shopping tool, a dating tool, an entertainment tool, 100 00:05:53,923 --> 00:05:57,958 and a way of skiving off work while making it look like you’re working or studying, 101 00:05:57,958 --> 00:05:59,976 which is what you may be doing now. 102 00:06:00,316 --> 00:06:04,673 Ultimately, though, you’re communicating, especially if you leave a comment, 103 00:06:04,673 --> 00:06:07,487 and that might make you a better human being.
