Also a rather significant achievement: people are actually watching these old videos. Seems like it stands a chance of being the widest distribution of such content ever, by a large margin. When was the last time most of us consumed century-old media of any kind?

Though I understand the historian side of things... every time I've seen major colorizing or cleanup efforts, I've seen far more people looking at them and talking about the history around that time than I'd normally see in, like, a year or more. Feels like a massive net-win to me.
