These networks do their internal polling and put on the shows people want to watch. The low information crowd wants “reality” shows, food shows with chefs screaming at each other and plenty of aliens, UFOs and Bigfoots. Those are what brings in the ratings.
We used to have a good weather channel, then NBC bought it, turned it into a weather history and sometimes weather channel.
We hated it when a tornado was on the way and we were getting some history show for an hour.
Not that station is gone, and DTV has a really good weather channel on now. 361.
Too many of the good History style channels have fallen to Reality shows. No history anymore. At least they are not hunting ghosts now.
