Creating assistive technologies that work seamlessly with all computing systems has been a daunting task where these technologies struggle to keep pace with an ever-evolving set of systems. This task becomes even more complex when you factor in the dynamic nature of the internet and its hundreds of millions of content creators. To fully appreciate the complex nature of creating accessible systems, it is important to see how we got to this point.
The following list outlines some (not all) of the many different web accessibility laws that have been enacted throughout the world. While some are more progressive than others and enforcement varies from region to region, more and more of the laws leverage the internationally recognized Web Content Accessibility Guidelines (WCAG) 2.0 as a key measure for testing and validating websites for optimal accessibility and usability.
