The first countries soon developed regulations or laws to implement these specifications. With the founding of the W3C in 1994 there was now expert body that also took it on itself to develop guidelines for barrier-free access to websites in addition to other standardization measures.

The Web Accessibility Initiative WAI of the W3C finally passed these guidelines itself in May of 1999 as Web Content Accessibility Guidelines . These guidelines in largely unchanged form became the foundation for the BITV Regulation for Barrier Free Information Technology of the German Law for Equal Opportunity for Disabled People of 2002 and for numerous other legal regulations in many countries around the world. In the years after the turn of the millennium the WAI then developed additional guidelines that apply to for example development of browsers that support accessibility and to other User-Agents UAAG in regards to authoring tools ATAG .

Thus the WCAG1 BITV despite their weaknesses are the only binding .
