they cant, even if they wanted. they cant. I think cable companies would like to do that (And change the same) because I bet some people would go for it even if it cost the same
But they cant break channels apart. I dont remember what the reason was but they cant
They can put them into groups, but not individual channels. At one time my cable company had any turner owned channel seperated and charged just for them, but now it's part of my tier package.
