HISTORY OF THE INTERNET

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

Hey there welcome to Life Noggin.

Thanks to this wonderful thing called
the Internet,

you are watching this video right now.

But how did the internet get to
where it is today?

There is so much internet history that
we couldn't possibly get to everything

in this short video. So we're definitely
going to have to make a second one.

Anyway let's get started: The internet
actually got its start over 50 years ago

and computers back then
filled up entire rooms.

Scientists and researchers used it for
years to communicate during the Cold War.

It was useful because if one computer
went down the others wouldn't follow.

In 1962, a scientist named JCR Licklider
proposed the idea of a network of

computers that could talk to one another.

In 1969 the first-ever message was sent
from one computer to another over the

ARPANET, the government's
computer network at the time.

ARPANET stands for Advanced
Research Projects Agency.

One was located in a research lab in UCLA
and the other at Stanford.

All the message said was LOGIN
and it didn't fail to crash the network.

Stanford only received the first two
letters of the message,

but hey you gotta start somewhere.

By the end of the year only four
computers were connected to this network.

In 1971, the University of Hawaii's
Aloha net was added followed by various

networks in London and Norway
two years later.

Also happening in 1971, Ray Tomlinson
was developing the first system to send

mail back and forth between the users
of ARPANET.

This would eventually be called
electronic mail or email for short.

The @ symbol was used to tell a
person's name and the host name apart.

With all of the networks floating
around there needed to be a way for all

of the computers on them to communicate
with other networks.

This is where computer scientist named
Vinton Cerf comes in.

He invented a way to introduce computers

across the globe to each other
in a virtual space.

This invention was called transmission
control protocol or TCP which was

followed by Internet Protocol or IP.
In the 80s scientists used surf's protocol

to send data back and forth but the 90s
is where it really all began.

In 1991 computer programmer named Tim
Berners-Lee invented the World Wide Web.

This wasn't just a data sharing space
for scientists anymore.

This was an entire network of
information that was accessible to

anyone with an internet connection.
You're using a browser right now

to watch this video and some of the
popular ones are

Firefox, Google Chrome, and Safari,
But in 1992 Erwise was created.

Earlwise was an internet browser and
the first to have a graphical interface.

A few browsers came before and after,
but in 1993 Mosaic was created

and it would popularize
surfing the web.

Mosaic influenced many of the browsers to
follow including Netscape Navigator in 1994.

This became the most popular web
browser at the time,

accounting for 90%
of the web usage in 1995.

In the early 90s, companies like AOL and
CompuServe

were starting to provide
dial-up internet access.

Dial-up is a method of connecting to
the Internet via telephone line.

Your telephone line was plugged
into a modem and the other end was

plugged into the phone jack.
There was a period in history where

you couldn't use your telephone in
the Internet at the same time.

Without the internet we obviously
wouldn't have things like

Facebook, Twitter, and YouTube,
But way more importantly,

we wouldn't be able to access
information in seconds.

We wouldn't be able to communicate with
people from around the world,

share ideas, and educate those who
might not get a chance elsewhere.

Also without the Internet, I'd actually
have to talk to someone

when I order a pizza,
which by the way,

was the first thing
ever purchased on the Internet.

How would your life be different
without the internet?
