It's happened to one show or network after another. The industry obviously thinks that all those frankly silly shows are better than their previous versions. Someone must be watching. Bit by bit, I just watch less and less TV. I didn't watch a lot anyway.
Example: I used to watch pawn stars because it was interesting to see the items that were brought in, learn their history, and hear about their values. Then The show started emphasizing the people working in the store, whom I couldn't stand, so I simply tuned out and have never watched again. That was probably two or three years ago. I never watch the Food Network now. I don't watch HGTV . I still love American pickers on history, but that's a rare exception. I have to go onto my iPad and find documentaries and other interesting shows because my brain can't take the, excuse me, ****** the regular TV is serving up these days.
