Overview
WorldWideWeb (later renamed Nexus to avoid confusion between the software and the World Wide Web) is the first web browser and web page editor. It was discontinued in 1994. It was the first WYSIWYG HTML editor.
The source code was released into the public domain on 30 April 1993. Some of the code still resides on Tim Berners-Lee's NeXT Computer in the CERN museum and has not been recovered due to the computer's status as a historical artifact. To coincide with the 20th anniversary of the research center giving the web to the world, a project began in 2013 at CERN to preserve this original hardware and software associated with the birth of the Web.
History
Tim Berners-Lee wrote what would become known as WorldWideWeb on a NeXT Computer during the second half of 1990, while working for CERN, a European nuclear research agency. The first edition was completed "some time before" 25 December 1990, according to Berners-Lee, after two months of development. The browser was announced on the newsgroups and became available to the general public in August 1991. By this time, several others, including Bernd Pollermann, Robert Cailliau, Jean-François Groff, and visiting undergraduate student Nicola Pellow – who later wrote the Line Mode Browser – were involved in the project.
Berners-Lee considered different names for his new application, including The Mine of Information and The Information Mesh, before publicly launching the WorldWideWeb browser in 1991. When a new version was released in 1994, it was renamed Nexus Browser, in order to differentiate between the software (WorldWideWeb) and the World Wide Web.
