I don't think the FCC is really interested in the a'la carte pricing at all, but rather they know it would be bad for the cable companies and are using it as a lever to force them to censor cable programming.
I feel a bit dirty for agreeing with a corporate entity, but I think the cable companies are right this time (as did the FCC before they decided it was convenient to disagree with them - flip floppers!)... A'la carte pricing ultimately wouldn't be good for the consumer. It MIGHT save you a little bit of money if you only watch one or two channels on any given month... Of course, you'd better hope those two channels are MTV and the NASCAR channel, since things like the History Channel likely won't be around very long. Smaller audience channels would have to be priced higher to make them worth carrying, which would in turn result in an even smaller audience than they had before when only the biggest fans of that channel turn out to pony up the cash.
Personally, I think I'd be fine with just TBS, TLC, Discovery, Comedy Central, Speed Channel and Spike TV. At $5 a channel plus $20 in assorted fees, I'd be about breaking even with my current cable bill... Once you account for the fact that a good half of those channels would likely cease to exist, I'd actually be saving money!
Likely, though, what you would have is bundles where you can choose, say 5 channels for the current Basic cable price, 10 for the next price up, and so on, or something to that effect. It's not like you're going to be able to get a single channel for just a couple of bucks a month if you so choose - it wouldn't be worthwhile for the cable companies to deal that way. So you end up paying the same amount, getting more "choice" in which channels you get, but not having as much of a variety of channels from which to make your selections.
You don't really think these companies are going to switch to a business model that's going to net them less profit, or that the government really has any interest in forcing them to do so, do you?
