All that old material isn't gone. PBS might not be streaming all ~4k episodes of the show but the Internet has made any media accessible if you know where to look. I'm surprised there isn't more data on what educational media is actually good or not. Because then we could just use that, because there are already millions of hours of this stuff made. Largely its because the profit is in making more of it, not making available all that which came before.
