If there was one site that would change the world for ever, it would be the first ever website, created by internet pioneer Tim Berners-Lee.

It went online on 6 August 1991 offering people help with using the brand new 'World Wide Web', rather modestly described as a "wide-area hypermedia information retrieval initiative aiming to give universal access to a large universe of documents".

If Berners-Lee had known what was to come, he might have added: "This is going to be awesome!"

Fascinating as it was back then, the web wasn't a whole lot of fun and after four years of pages created by scientists and academics, David Bohnett and John Rezner, who ran a web directory called Beverly Hills Internet, turned their company into GeoCities, giving anyone the ability to create their own site for free.

"There was a time when half the internet seemed to be on GeoCities and I don't think that this can be underestimated," says Rob 'CmdrTaco' Malda, founder of Slashdot. "GeoCities made it possible for anyone to put something online for nothing. This was a huge deal."
