I think TV is it's own thing, 'real' woodworking can be very boring and is done at quite a slow pace with hand tools a pace that modern life isn't used to seeing, which without professional editing doesn't make great entertainment, most of the big youtubers are very estute with editing and production, or they hire somebody when they get enough attention, I think youtube can be just as bad as TV though, there's plenty of rubbish on there as well as the good stuff, I get the most valuable information from books.
