The most graphical service on the Internet, the Web also has the most sophisticated linking abilities .

World Wide Web Consortium (W3C)

An international industry consortium that is jointly hosted by the Massachusetts Institute of Technology Laboratory for Computer Science (MIT/LCS) in North America, by the Institut National de Recherche en Informatique et en Automatique (INRIA) in Europe, and by the Keio University Shonan Fujisawa Campus in Asia. W3C was founded in 1994 to develop common standards for the World Wide Web. Initially, the W3C was established in collaboration with CERN, where the Web originated, with support from the Defense Advanced Research Projects Agency (DARPA) and the European Commission.
