Well, there’s certainly that. But even then, I’d think that a lot of videos could be made to be more concise. I was actually wondering whether YouTube creators get paid based on the amount of time they have people watch, since that’d explain drawing things out. My impression, from what I could dig up in a brief skim, is that they’re indirectly linked — apparently, YouTube shows ads periodically, and the more ads shown, the more revenue the creator gets. So there would be some level of incentive to stretch videos out.
