An advertising supported YouTube creator would be delighted!

No, literally a lot of creators target this market now — for instance by making a mega mix of their existing content which runs for two to three hours. Or releasing a video „xxx hours of yyy to fall asleep to“

It’s the new ‚meta’, apparently a big part of the YouTube algorithm is watch time, and it doesn’t know if the viewers are awake or not. Even if those viewers aren’t being shown adverts, it means your other videos may get additional promotion. Plus if your viewers have YouTube premium I believe watch—time literally translates directly to payment rates.

How it's Made does it for me. Based on a lot of the youtube comments, there are quite a lot of others as well!
