World Wide Web

12 March 1989

The World Wide Web began as a proposal written by the British computer scientist Tim Berners-Lee while working at CERN, the European particle physics laboratory near Geneva. He suggested a system in which documents stored on different computers could be linked together by hypertext, so that researchers could easily share information. With colleagues he developed HTML, HTTP and web addresses, and wrote the first web browser and server in 1990. The web opened to the public in 1991, and CERN released the underlying technology royalty-free in 1993, which helped it spread quickly, especially after the Mosaic browser appeared. The web is an application that runs on the Internet, the network of networks, and not the Internet itself.
