I agree, History on YT is bloody brilliant! I often fall asleep listening to People Profiles, but there is loads to choose from. Just tons. From all over the world and about practically every civilization that has ever existed.
The range of political coverage is immense. You can access the major news corps of virtually every country as well as Sky, BBC, etc I actually prefer Sky on YT and Sky Australia
Anthropology, psychology, nature programs, maths, survival skills, lectures, debates, clothes design, runway fashion, history of Art, Royal coverage, languages, cooking, science, philosophy, history, crafts, live court cases, historical enactments, documentaries, how to's, celebrity scandals, live international sporting competitions, podcasters, financial news.
If I were exiled to a deserted island, and there was only one SM website I could use. It would be YT.
That all said OP, I think your DH ought to have been more accommodating and you should have found something together to watch. His reaction, considering how much you had done before relaxing was OTT.
