The W3C was founded in October 1994 to lead the World Wide Web
to its full potential by developing common protocols that promote its evolution and ensure
its interoperability. We are an international industry consortium, jointly hosted by the
Massachusetts Institute of Technology Laboratory for Computer Science [MIT/LCS] in the
United States; the Institut National de Recherche en Informatique et en Automatique
[INRIA] in Europe; and the Keio University Shonan Fujisawa Campus in Japan. Services
provided by the Consortium include: a repository of information about the World Wide Web
for developers and users; reference code implementations to embody and promote standards;
and various prototype and sample applications to demonstrate use of new technology.
Initially, the W3C was established in collaboration with CERN, where the Web originated,
with support from DARPA and the European Commission. For details on the joint initiative
and the contributions of CERN, INRIA, and MIT, please see the statement on the joint World
Wide Web Initiative.
The Consortium is led by Tim Berners-Lee, Director and creator of the World Wide Web, and Jean-François Abramatic, Chairman. W3C is funded by Member organizations, and is vendor neutral, working with the global community to produce specifications and reference software that is made freely available throughout the world.

HTML Primer 1996 from NCSA (the National Center for Supercomputer Applications) is where Mosaic (the precursor
to Netscape) was developed. The Primer is elementary, but nice.
