I can't speak specifically to "historical documentation", but in a field that interests me, which I suppose we could call "music, musicking and music theory", YT is better than anything I'm aware of from TV with the possible exception of the Bernstein lectures.

For a TV station/network/organization to have exposed us to just one of (for example): David Bruce, 12Tone or Adam Neely would be remarkable enough, but we actually get all three and then a whole bunch of others who are in the same general ballpark.

For example, the "David Bennett Piano" channel, produced by a young UK piano player, has a 15 minute segment that is hands-down the best explanation of why many musical cultures settled on dividing the octave into 12 tones. It's better than anything I've ever seen on TV.

It is true that these tend to be shorter and more focused presentations than series like Connections. I'm not sure I see anything inherently wrong with that. It's also true that they don't score always hit it out of the park for every "episode" they produce (unlike much the more collaborative processes that would have led to each episode of Connections). But I'm not sure I see much a problem with that either.
