World Wide Web conference opens, 20 years after its invention

British software genius Tim Berners-Lee, one of the founders of the system, will give a keynote talk on Wednesday "which will reflect on the last 20 years and look forward to the next 20 years" of the Web.

Spanish Crown Prince Felipe and his wife Letizia are scheduled to attend the talk.

Over the five days of the 18th international World Wide Web conference, 105 research papers will be presented covering topics including interactive television, mobile web applications and the challenge of new media to traditional media.

The conference is organised each year by the International World Wide Web Conferences Steering Committee (IW3C2), a professional organization registered in Switzerland which promotes Web research and development.

It was held in China last year. The US will hold the next conference in 2010.

With the help of other scientists at the European Organisation for Nuclear Research (CERN), Berners-Lee set up the system to allow thousands of scientists around the world to stay in touch.

In March 1989, the young Berners-Lee handed his supervisor in Geneva a document entitled 'Information Management: a proposal."

The supervisor described it as "vague, but exciting" and gave it the go-ahead, although it took a good year or two to get off the ground and served nuclear physicists in Europe initially.

The WWW technology -- which simplifies the process of searching for information on the Internet -- was first made more widely available from 1991 after CERN was unable to ensure its development, and the organisation made a landmark decision two years later not to levy royalties.

As recently as 1994 there were only 500 fairly modest Web sites worldwide, according to Microsoft. Now there are millions.

Berners-Lee, now a researcher at Massachusetts Institute of Technology in the United States and a computer science professor at Southampton University in Britain, still heads the World Wide Web Consortium (3WC) that coordinates development of the Web.
