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.
First International Conference on the World-Wide Web
The event was organized by Robert Cailliau, a computer scientist who had helped to develop the original WWW specification, and was hosted by CERN. Cailliau had lobbied inside CERN, and at conferences like the ACM Hypertext Conference in 1991 (in San Antonio) and 1993 (in Seattle). After returning from the Seattle conference, he announced the new World Wide Web Conference 1. Coincidentally, the NCSA announced their Mosaic and the Web conference 23 hours later.
