Cosmos 2014
As I mentioned on the main astronomy page, I like this very much, and would recommend it as a good introduction to the history of astronomy and of the history of the universe. I find it holds up pretty well to the 40 years since it’s release, and the edition I got from the library was the 20th anniversary extended edition with updates at the end of most episodes.
