Who Invented the Internet?

The internet, a whole bunch of computer networks connected to each other, and then there’s the World Wide Web, a way of making it easier to share information using all those interconnected computers.

The internet as we know it today was at least 40 years in the making.

One popular but wrong story is that the internet was developed by the USA so they had a communication network that would survive a nuclear war.

According to one of the founders of the first network, the ARPANET, in the 1960s, this first network experiment wasn’t about communication at all; it was about optimizing processor usage, or time-sharing, which basically meant that scientists could share computer power, too.

That was because until the 1960s there was basically no network — you had big machines called mainframes which sat in the room and processed computing tasks one at a time.

With time-sharing, these behemoths could process several tasks at a time, which meant their power could be used by several scientists at once.

And, obviously, once you start connecting computers together, you start to wonder about what you need to do to make communications between them easier.

Scientists around the world were trying to solve this problem. So let’s look at some other key concepts that were developed elsewhere.

Starting with packet switching.

In Britain, there was a commercial network, developed by the National Physical Laboratory, but which never really got off the ground because it didn’t get funding. But they did come up with the idea of packet switching, a way of avoiding congestion in busy networks by cutting up data at one end and putting it back together at the other.

The French also played a role. They were working on a scientific network called CYCLADES, but they didn’t have a big budget, so they decided to work on direct connections between computers, as opposed to working with gateway computers.

Now, as an aside here, this, admittedly, isn’t very scientific, but according to one theory, a spin-off of their research was the word “internet”. But you don’t have to believe it if you don’t want to.

So, now it’s the early 1970s.

There’s quite a lot of computer infrastructure, but communication is awkward and patchy because different networks can’t talk to each other.

TCP/IP solves this problem.

The TCP/IP protocols form the basic communication language of the internet, which labels the packets of data and makes sure that even though some pieces of the same data take a different route, they all arrive at their destination and can be reassembled.

Networks really began communicating with each other in 1975, so you could argue that was the beginning of the internet.

The email was also very important. It was developed for ARPANET in 1972.

Most internet traffic in 1976 was an email because academics thought electronic post-it notes were dead-core.

With networks that could talk to each other, communication was becoming easier. But all this communication was just text-based, and it was pretty ugly to look at.

In the 1980s, a Brit called Timothy Berners-Lee spent time with CERN, the European Organization for Nuclear Research, where physicists are trying to work out what the universe is made of.

He wanted to manage the scientists’ information and make it possible for them to share and interconnect their work easily, making progress more likely.

He did so by inventing an interface using HTTP, HTML, and URLs that made internet browsers possible. He called his browser the World Wide Web.

So he didn’t invent the internet, but he did invent the Web.

The first-ever website, which he created, was at CERN in France in August 1991.

So, once the initial infrastructure was in place, the key technologies had been invented, internet message boards exploded in the 1980s, the phone companies saw the commercial potential of digital communication, web browsers spread like wildfire in the early 1990s, and ordinary people discovered email, then the internet expanded rapidly and steadily and became workable for the masses from about 1995.

The internet exists because we need to communicate, and most of us like doing it. That’s why humans have become the dominant species on Earth.

You could argue that the internet is a natural evolutionary step and a manifestation of that need.

It wasn’t invented by anyone in particular, but when the building blocks were put together by all those cool scientists from all over the place, the internet became a communication tool, a retail tool, a research tool, a propaganda tool, a spying tool, a shopping tool, a dating tool, an entertainment tool, and a way of skiving off work while making it look like you’re working or studying, which is what you may be doing now.
