There’s plenty of interesting stuff going on in the world. Reporting on it doesn’t maximize profit.
CNN used to have shows about fashion, sports, entertainment, the arts, world affairs. They figured out that just having talking heads blab and argue with each other was cheaper.
CNN headline news used to be just a 30 minute broadcast about the day’s major headlines repeated on a loop every half hour. They didn’t really fill the entire 24 hours with different stories all day long.
Similarly ESPN used to show sports of all kinds. Rugby, Soccer, bowling, snooker/billiards. Again, it’s just taking heads now.
