Discovery
Twenty years after the emergence of the world wide web, Rory Cellan-Jones of the BBC World Service’s Discovery series looks at the science driving its third decade.

Web 3.0 promises a world where people and objects are seamlessly connected through an all pervasive network, no longer controlled through devices such as mouse and keyboards but through speech, gestures and even our very thoughts. It is a web that will become truly mobile and global.

Who will ultimately control the web – big business or the community? And will the developing world finally take centre stage in this new silicon Babylon?
