Did you ever consider the possibility that maybe they couldn't make money without the commercials?
They are not a charity.
neither is Turner movie classics.. but guess what. they still have the same format.. and I watch them.. I used to watch AMC almost every day.. and I can't tell you how many vhs tapes I have made from their programming.. but as soon as they went to commercials, I stopped.. the same with fox movie channel. Hey you start and set the format, you can't change horses in midstream and expect people to stay with them..
