Of
all the cool claims to fame, inventing the world wide web has to be the best.
That honor lies squarely with Tim Berners-Lee.
While working as a contractor at CERN, he came up with a system called ENQUIRE, which enabled sharing and updating information between researchers using hypertext.
It was in 1989 when he returned to CERN that he was an opportunity to link hypertext to the internet (itself only actually a way of connecting computer network across the globe) and the World Wide Web was born.
He designed and built the web browser, created the first web server and, in short, changed the entire world as we know it. We're now so reliant on the internet that it's impossible to imagine life without the world wide web.
