The World Wide Web, which has radically changed the way we live, has just turned 25.

On 12 March 1989 Tim Berners-Lee, a scientist working at CERN, submitted an idea for an infrastructure enabling information to be shared over the Internet. 

In a memo to his boss, Berners-Lee described his idea for "Information Management: A Proposal" which stated that  "a 'web' of notes with links (like references) between them is far more useful than a fixed hierarchical system."

The first web pages were created in 1991, just seven years before the web was being used by a quarter of the US population, the Economist writes in its blog.

Berners-Lee was asked in a Q&A session on Reddit what is the most unexpected main use of the Internet– he simply said ‘kittens’.

Further commenting on his invention from today's perspective, Berners-Lee said he was both excited and concerned about the future of the online world.
