He did. In 1994 Berners-Lee left CERN to join the Laboratory for Computer Science at MIT. The task of the World Wide Web Consortium, or W3C, was to set standards for the Web. The immediate task of the W3C was to set a standard version of HTML, which was compatible with every vendor. The W3C has since went on to create standards for CSS, SOAP, and XML.
The W3C views the World Wide Web as an information space which resides on the Internet (a global computer network). The World Wide Web is identified on the Internet by three key components (which Tim Berners-Lee is credited with inventing),
As Berners-Lee set the specifications for these three crucial elements of the Web, and, of as 2012, still heads the W3C, it's role remains to set standards for these elements, as well as for emerging technologies: such as XML.
What the W3C decides to do is based upon what it's 380+ members tell it to do. There has been a suggestion, even a criticism, that the W3C panders to what big business and large software houses desire. The W3C is funded by donations and from the fees levied upon it's members; which is largely dominated by large companies.
In Berners-Lee own words, the W3C was created for the purpose of:
"developing common protocols that promote its evolution and ensure its interoperability. W3C has around 400 Member organizations from all over the world and has earned international recognition for its contributions to the growth of the Web."
W3C, as an organisation, is amongst the most important for the developing the World Wide Web: due to the fact that they create the majority of design languages and protocols for the World Wide Web. W3C have developed: HTML, CSS and XML. Currently (2013), the most exciting design protocol W3C are working on is XML: which is playing an increasingly important role in the exchange of a wide variety of data on the World Wide Web.
Berners-Lee knighted by the Queen of England for being the creator of the World Wide Web.
This honor was announced in 2004 by Buckingham Palace as part of the New Years honours list.
Berners-Lee currently served as director of the World Wide Web Consortium
when the honour was announced. Berners-Lee wrote in reply "The dream behind the Web is of
a common information space in which we communicate by sharing information,".
