Am I alone in thought that TV, has become less about entertainment and more about teen gossip?

Networks keep killing one show after another and everytime they replace a show its a show about reality tv, or gossip like TMZ, or another cooking show, or health show, or some sort of talent show.
There is the cooking channel, the fitness channel and of course MTV.
So why do the regular channels feel they can compete with channels that are all ready about a certain topic. Why must they cancel out comedys or drama shows? They are all dying quickly.
Well one good thing I suppose. I’ll have more time to read or be on fluther.
