The W3C, or World Wide Web Consortium, is an international body made up of Member organizations, full-time staff, and the public working together to establish Web standards. Their mission: "To lead the World Wide Web to its full potential by developing protocols and guidelines that ensure long-term growth for the Web."
The Web standards promoted by the W3C include "non-proprietary open standards for Web languages and protocols" (HTML, XHTML, XML, and CSS) to avoid "market and Web fragmentation." Essentially, these Web standards are the grammar rules for the common language that allows the various web browsers to bring data and text from the Internet to your computer.
