A timeline of CAST--from special learners to all learners

I came across a timeline of CAST on its website. This is quite interesting to read because it reveals the history of the organization and how it grows along with the emergence of universal design concept in architecture and shifts its focus from serving diverse learners to all learners. You can also get a sense of how UDL ideas interplay with emerging technologies and federal laws. The timeline shows that CAST has played an active role in advocating for all learners all these years by partnering up with various research and software development agencies to produce free or low-cost software that can benefit all learners.
