Thank you for this. You linked to the youtube videos but I watch the PBS app on my Roku all the time and it's horrible at recommending what I should watch. "Watched 'City in the Sky' [a 3-part series about airports and planes]? You'll love Downtown Abbey or The Great British Baking Show!" I'm always looking for some actual good/educational shows on there, and there's so many great hidden gems, but they're all... hidden.
