The document summarizes the development of web accessibility over the past 10 years from a UK perspective in 4 stages: 1) Early days focused on guidelines to make the web accessible to disabled users. 2) Accessibility became part of web standards and was embraced by developers. Research showed guidelines were not enough. 3) Surveys found many sites still not conformant with guidelines, but some disabled users could use sites successfully. A holistic approach was needed. 4) Web 2.0 introduced new challenges. A practical view recognizes value of multiple formats. Tools now support inclusive authoring. Maintaining accessibility remains an ongoing challenge.
