So, if it's just cable, then how did they support themselves?
Cable companies charge you to carry your station, you have to pay your employees and pay for your content... How does a station without commercials support themselves other than the PBS model with Pledge drives and Government proceeds?
Channels like IFC and TCM, which aren't basic channels, but aren't "premium " channels that you pay an individual set fee for, get paid by the cable, or satellite, company, on a per-viewer basis. Of course, the money they get comes from what you pay your service provider.
TCM no longer owns Turner's film library, which includes WB films. They have to pay for every film they run. But, I'd guess that the negotiations with the Turner film library are easier, and cheaper, than with other sources.
GKE, yes, I know, losing the IFC hardly makes it difficult to have good things to see. I don't have a computer, or ISP at home, so I can't stream. But, I do have free access to a library of well over 40,000 DVDs, where I work. Besides that, I have lots of DVDs I've burned myself, and haven't had time to watch yet. But, the IFC, and Sundance, both showed films I hadn't heard of, that I checked out, and found to be quite good. They weren't just a source of programming, but a source of knowledge of what films there were, in their favored genres.
Oh, I have read that
Inception holds the new record for bluray sales v DVD sales, so I guess it's out!
