This episode of Life Noggin is brought[br]to you by Audible.

0:00:02.516,0:00:04.580
Hey there welcome to Life Noggin.

0:00:04.580,0:00:06.488
Thanks to this wonderful thing called [br]the Internet,

0:00:06.488,0:00:08.606
you are watching this video right now.

0:00:08.606,0:00:10.770
But how did the internet get to [br]where it is today?

0:00:10.770,0:00:13.529
There is so much internet history that[br]we couldn't possibly get to everything

0:00:13.529,0:00:16.614
in this short video. So we're definitely [br]going to have to make a second one.

0:00:16.614,0:00:20.691
Anyway let's get started: The internet [br]actually got its start over 50 years ago

0:00:20.691,0:00:23.136
and computers back then [br]filled up entire rooms.

0:00:23.136,0:00:26.909
Scientists and researchers used it for[br]years to communicate during the Cold War.

0:00:26.909,0:00:29.877
It was useful because if one computer [br]went down the others wouldn't follow.

0:00:29.877,0:00:34.840
In 1962, a scientist named JCR Licklider [br]proposed the idea of a network of

0:00:34.840,0:00:36.667
computers that could talk to one another.

0:00:36.667,0:00:40.910
In 1969 the first-ever message was sent [br]from one computer to another over the

0:00:40.910,0:00:43.328
ARPANET, the government's [br]computer network at the time.

0:00:43.328,0:00:46.139
ARPANET stands for Advanced[br]Research Projects Agency.

0:00:46.139,0:00:49.861
One was located in a research lab in UCLA [br]and the other at Stanford.

0:00:49.861,0:00:53.206
All the message said was LOGIN[br]and it didn't fail to crash the network.

0:00:53.206,0:00:55.979
Stanford only received the first two [br]letters of the message,

0:00:55.979,0:00:57.564
but hey you gotta start somewhere.

0:00:57.564,0:01:00.522
By the end of the year only four [br]computers were connected to this network.

0:01:00.522,0:01:05.416
In 1971, the University of Hawaii's [br]Aloha net was added followed by various

0:01:05.416,0:01:07.651
networks in London and Norway[br]two years later.

0:01:07.651,0:01:11.458
Also happening in 1971, Ray Tomlinson [br]was developing the first system to send

0:01:11.458,0:01:13.947
mail back and forth between the users [br]of ARPANET.

0:01:13.947,0:01:17.552
This would eventually be called [br]electronic mail or email for short.

0:01:17.552,0:01:20.762
The @ symbol was used to tell a [br]person's name and the host name apart.

0:01:20.762,0:01:23.819
With all of the networks floating[br]around there needed to be a way for all

0:01:23.819,0:01:26.401
of the computers on them to communicate[br]with other networks.

0:01:26.401,0:01:29.587
This is where computer scientist named [br]Vinton Cerf comes in.

0:01:29.587,0:01:31.712
He invented a way to introduce computers

0:01:31.712,0:01:33.947
across the globe to each other [br]in a virtual space.

0:01:33.947,0:01:38.063
This invention was called transmission [br]control protocol or TCP which was

0:01:38.063,0:01:42.483
followed by Internet Protocol or IP.[br]In the 80s scientists used surf's protocol

0:01:42.483,0:01:45.955
to send data back and forth but the 90s [br]is where it really all began.

0:01:45.955,0:01:51.440
In 1991 computer programmer named Tim [br]Berners-Lee invented the World Wide Web.

0:01:51.440,0:01:53.964
This wasn't just a data sharing space[br]for scientists anymore.

0:01:53.964,0:01:57.027
This was an entire network of [br]information that was accessible to

0:01:57.027,0:02:00.341
anyone with an internet connection.[br]You're using a browser right now

0:02:00.341,0:02:02.632
to watch this video and some of the[br]popular ones are

0:02:02.632,0:02:07.174
Firefox, Google Chrome, and Safari,[br]But in 1992 Erwise was created.

0:02:07.174,0:02:10.972
Earlwise was an internet browser and [br]the first to have a graphical interface.

0:02:10.972,0:02:15.343
A few browsers came before and after, [br]but in 1993 Mosaic was created

0:02:15.343,0:02:17.353
and it would popularize[br]surfing the web.

0:02:17.353,0:02:22.447
Mosaic influenced many of the browsers to [br]follow including Netscape Navigator in 1994.

0:02:22.447,0:02:24.832
This became the most popular web[br]browser at the time,

0:02:24.832,0:02:28.560
accounting for 90%[br]of the web usage in 1995.

0:02:28.560,0:02:31.388
In the early 90s, companies like AOL and [br]CompuServe

0:02:31.388,0:02:33.611
were starting to provide [br]dial-up internet access.

0:02:33.611,0:02:36.855
Dial-up is a method of connecting to [br]the Internet via telephone line.

0:02:36.855,0:02:39.773
Your telephone line was plugged[br]into a modem and the other end was

0:02:39.773,0:02:42.533
plugged into the phone jack.[br]There was a period in history where

0:02:42.533,0:02:45.680
you couldn't use your telephone in [br]the Internet at the same time.

0:02:45.680,0:02:48.026
Without the internet we obviously [br]wouldn't have things like

0:02:48.026,0:02:50.932
Facebook, Twitter, and YouTube,[br]But way more importantly,

0:02:50.932,0:02:53.602
we wouldn't be able to access [br]information in seconds.

0:02:53.602,0:02:56.622
We wouldn't be able to communicate with[br]people from around the world,

0:02:56.622,0:03:00.761
share ideas, and educate those who [br]might not get a chance elsewhere.

0:03:00.761,0:03:03.486
Also without the Internet, I'd actually [br]have to talk to someone

0:03:03.486,0:03:05.606
when I order a pizza, [br]which by the way,

0:03:05.606,0:03:08.333
was the first thing [br]ever purchased on the Internet.

0:03:08.333,0:03:10.066
How would your life be different [br]without the internet?
