I've been giving this some thought as a member of the media octopus. I'm obviously reluctant to accept the blame wholesale.
I think it's fair to say that in a high-effort media production environment, the focus is on things that you can convince the audience they'll love and can only get from you. There have been a million takes on "hospital" but "ER" or "Gray's Anatomy" are particular takes that resonated.
In a low-effort media production environment, the focus is on things you can throw in front of the audience that they won't bother switching away from. "here's an industry with people in it that do stuff" is Orange County Choppers, is Duck Dynasty, is Property Brothers, is Pawn Stars, is whatever. They're completely interchangeable. We can all switch hit from one dumb hosted hickfest to another. I once shot a "pickers"-type pilot that finished at the Pasadena antique fair, something that happens every month. We were one of three "pickers" - type pilots shooting that day. It's fucking pathetic.
Thing of it is, we'll all do the high-value shit over the low-value shit (I'm lucky enough that I don't have to bother with the low-value shit anymore). But very few people put the effort into an "ER" or "West Wing" or "Game of Thrones." They'd rather half-watch 4 episodes of Intervention because they can get other shit done while they're doing it.
I'm certainly guilty of this.
