I have found out so far that when the first computers were invented in the 1950s scientists staright away started to try to connect them together.
This was the start of the idea of the internet.
It was a man called Tim Berners-Lee about 30 years later who made a way for this to work for everyone.
The internet today is made up of computers all over the world which are connected together because of him.
If it wasn't for him I wouldn't be able to watch my favourite music videos on You Tube, play online games or make websites like this one for homework projects!
