I've been tracking this...
As you know, .gov sites are expected to meet Section 508 web standards, as do sites that do business with the gov such as GSA contracts. More and more .edu sites choose to be compliant because it makes sense to and to avoid lawsuits.
What you may not know is that there is a gigantic spike in lawsuits by the disabled against ANY AND ALL websites they can not use. I'm putting together an article on this. These lawsuits are being settled out of court and the website owners are losing. Retail is the number 1 target and the financial and banking industry being hammered.
SUMMARY: We, the Architectural and Transportation Barriers Compliance Board (Access Board or Board), are revising and updating, in a single rulemaking, our standards for electronic and information technology developed, procured, maintained, or used by Federal agencies covered by section 508 of the Rehabilitation Act of 1973, as well as our guidelines for telecommunications equipment and customer premises equipment covered by Section 255 of the Communications Act of 1934. The revisions and updates to the section 508-based standards and section 255-based guidelines are intended to ensure that information and communication technology covered by the respective statutes is accessible to and usable by individuals with disabilities.
DATE: This final rule is effective March 20, 2017. However, compliance with the section 508-based standards is not required until January 18, 2018. Compliance with the section 255-based guidelines is not required until the guidelines are adopted by the Federal Communications Commission. The incorporation by reference of certain publications listed in the final rule is approved by the Director of the Federal Register as of March 20, 2017.
