World Wide Web
The World Wide Web, also known as the WWW and the Web, is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and accessible via the Internet. English scientist Tim Berners-Lee invented the World Wide Web in 1989. He wrote the first web browser in 1990 while employed at CERN near Geneva, Switzerland. The browser was released outside CERN in 1991, first to other research institutions starting in January 1991 and to the general public on the Internet in August 1991.
History of the World Wide Web
Initially, a web browser was available only for the NeXT operating system. This shortcoming was discussed in January 1992, and alleviated in April 1992 by the release of Erwise, an application developed at the Helsinki University of Technology, and in May by ViolaWWW, created by Pei-Yuan Wei, which included advanced features such as embedded graphics, scripting, and animation. ViolaWWW was originally an application for HyperCard. Both programs ran on the X Window System for Unix. In 1992, the first tests between browsers on different platforms were concluded successfully between buildings 513 and 31 in CERN, between browsers on the NexT station and the X11-ported Mosaic browser.
