WorldWideWeb discoverer or inventor Tim Berners-Lee
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.The team created so called "passive browsers" which do not have the ability to edit because it was hard to port this feature from the NeXT system to other operating systems. Porting to the X Window System was not possible as nobody on the team had experience with the X Window System.Berners-Lee and Groff later adapted many of WorldWideWeb's components into a C programming language version, creating the libwww API.A number of early browsers appeared, notably ViolaWWW. They were all eclipsed by Mosaic in terms of popularity, which by 1993 had replaced the WorldWideWeb program. Those involved in its creation had moved on to other tasks, such as defining standards and guidelines for the further development of the World Wide Web (e.g. HTML, various communication protocols).On 30 April 1993, the CERN directorate released the source code of WorldWideWeb into the public domain. Several versions of the software are still available on the web in various states. Berners-Lee initially considered releasing it under the GNU General Public License, but after hearing rumors that companies might balk at the concept if any licensing issues were involved, he eventually opted to release it into the public domain.
