HISTORY OF THE INTERNET

(male narrator)
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 possible get

to everything in this short of video.
So we are definitely going to have to make

a second one
Anyway, let's get started.

The internet actually got its start
over fifty 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 Lickleder 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 Project Agency.

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

All the message said was "Log in"
and it didn't fail or 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 Thomlinson

was developing the first system to send
mail back and forth between 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 appart.

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

for all the computers on them
to communicate with other networks.

This is where computer scientists
name 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 80's, scientists used

Cerf's protocol to send data
back and forth,

but the 90's is where it all began.
In 1991, computer programer named

Tim Berners-Lee invented the
World Wide Web.

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

This was an entire network of information
that was accessible to anyone

with an internet connection.
You are using a browser right now

to watch this video.
Some are the popular ones are

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

Erwise 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
of the time accounting for 90%

of web usage in 1995.
In the early 90's companies like

AOL and Compuserve were starting
to provide dial-up internet access.

Dial-up is a method of connecting
to the internet via a 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 and

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 commuicate

with people around the world,
share ideas and educate those

who might not get a chance elsewhere.
Also without the internet,

I would 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?
