Because that's what it seems like. Even History channel, Animal Planet, Discovery etc are no longer as educational as they used to be.
That drives me nuts. The History and Discovery channels especially. However, i like
American Pickers on History Channel. Then there's
Pawn Stars and
Cajun Pawn Stars. WTF do pawn shops have to do with history? NOTHING! Take em off! I think you were better off being known as the "Hitler Channel".
Then there's the Discovery Channel, which has
Deadliest Catch, which isn't too bad. But then we've got other fisherman shows like
Lobster Wars and
Swords, a bunch of shows with Bear Grylls wannabes and we end the line-up with gun dealers. Cut the crap out and bring back
Mythbusters re-runs and stuff on sharks. At least Mythbusters has science and entertainment (especially the explosions). Put the whiny New England fishermen on an Outdoorsmen-type channel and put the gun dealers on Spike.
You also failed to mention 2 other channels that have fallen ill with the "Reality TV" disease. TLC and Sci-fi (now known as "Siffy).
TLC shows a program that exploits kids under the age of 6 for the sake of some parental ego boost (and is no doubt mostly viewed by perverts), a fraud medium from Long Island and people who go on shopping sprees with shopping bags full of coupons.
And as for Siffy, when it's not airing crappy movies that rival those seen on Mystery Science Theater 3000, it has shows that are either rip-offs of Ghost Hunters or is a Reality show about competing Sci-fi make-up/Special-effects artists.
