The World Wide Web was created in 1989 by a young British computer scientist called Tim Berners-Lee. It's been called one of the greatest inventions of the 20th century and has revolutionised the way we live and interact with each other and the world, and share information and knowledge. Louise Hidalgo talks to fellow computer scientists Ben Segal and Jean Francois Groff who worked at the European scientific research centre, Cern, where Tim Berners-Lee created the World Wide Web, and helped him realise his vision.
