Cable is not regulated, they can do what ever they want .... so you know, Cable business does not make the movies, series, etc. They are the company that pays networks for their products, the networks pay the studies for their series, movies, etc. The movies and series are products that have prices basd on how much they cost, for example a new series is cheap and will often have few commercials. While othere series have proven themselves to have high ratings, and cost the network and thus the cable companies more to show. To off-set cost and make profit, high rated shows have lots of commercials, knowing that each one is expensive and a cash cow. What most people do not know about cable companies, is that due to the companies like DISH and DIRECT TV, cable has not had the freedom to raise their prices as much as they life and make pennies on the television they broadcast. They make the majority of their profit on high speed internet and phone service, phone service being new to their profit margin and yet they are making good money with it.
So in summary, complaining about a nonregulated company and thinking you can sue them, sue them for what? If they are not regulated, being told what to do and how (like phone companies are). Then you would be basically told, 'yeah right!' by any lawyer you talked too ... who would most likely think you were nuts for suggesting it.
Just an FYI, I am not pulling this information out of my ass ... I know and work in the industry. Nice thought though, but it is going to get worse and not better.
