They haven't offered free previews of premium channels in recent memory. They used to have an answer about it in the customer support section of the website but I couldn't find it. The answer was something like they didn't offer it because some people were offended by some programming and couldn't block it for only certain people. Some kid must have saw some topless women once and some lady went nuts on them.
Well, the argument shouldn't hold water anymore, I was watching HD Monsters, which I understand is included free with my Cable service last night at about 7 pm.
I lost count of how many F bombs were dropped during the movie! So what excuse will Cablevision give now?
