Monday at 10 PM EST Court TV is airing the first of a three part series on adult entertainment. Might be worth a watch, but I think they're going to portray it badly. They were talking about drugs, murder and the darker side of the industry. It's called "Adults Only: The Secret History of the Other Hollywood".

Lots of reading on the industry there.
