The internet was created because humans used computers to communicate.
Nowadays, however, we are used to using smartphones, laptops and tablets for online chats, but how it all began is a story that has been told in every episode of the internet series The IT Crowd.
The IT crowd is a fictional organisation of internet users, who all share the same idea of how the internet came to be.
Their name comes from a TV show about a small group of internet enthusiasts who create a global internet and then have to deal with the fallout.
The internet started in 1988 as a simple way to share information between different groups of people who could not communicate using a computer.
It has grown into a network of more than half a billion people worldwide, and today the internet is used in almost every aspect of our lives, from buying groceries to watching television programmes to playing games.
The BBC series is the first to take a serious look at the history of the web, starting with its creation.
And in a world where social media is increasingly important, it shows how the rise of the Internet was not a natural outcome of a digital revolution.
