This article is a follow up to a recent twitter chat, sharing a timeline of the development of accessibility resources.
This timeline is non-exhaustive, there will no doubt be things that I've missed or am not aware of, and there are a few internal sets of guidelines that can't be shared publicly too.
But hopefully it will be an interesting read, and give a sense of where we have come from, how knowledge and resources have grown, evolved, built upon one another, and how many passionate people from all across the industry have helped to push the field forward.
