The Verge had a series called Accessibility week.

The Hidden History of Screen Readers is a non-technical article from Sheon Han which tells, well, the history of screen readers. It's a very descriptive and accurate title.

It's nice to see these well-written articles containing links to additional resources. I have the impression that we are all so caught up in the technicalities that we forget how things came to be, and we might miss some contexts.
