World Wide Web Consortium
The World Wide Web Consortium (W3C) makes technical recommendations to Web site authors, including ways to make websites universally accessible. 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. They are an international industry consortium, jointly hosted by the Massachusetts Institute of Technology Computer Science and Artificial Intelligence Laboratory (MIT/CAIL) in the United States; the European Research Consortium for Informatics and Mathematics (ERCIM) in France, the Keio University Shonan Fujisawa Campus in Japan and the Beihang University in China.
As a collaborative medium, the Internet demands that people be able to create content—not just read it—regardless of disability. A subgroup of W3C, the Web Accessibility Initiative (WAI) has produced guidelines that explain how to make web content more accessible to people with disabilities.  This refers to text, images, sounds, and the code to create this information.  To read these guidelines, visit the Web Content Accessibility Guidelines (WCAG) Overview
