Re: We are considering cancelling cable
I don't think it is particularly about broadcast rules, as far as I know HBO get away with the same thing. The reason that they can get away with more is the subscription model; they are not trying to keep advertisers happy.
This is from the HBO wiki page:
"HBO does not carry "normal" commercials; instead the network runs promotions for upcoming HBO programs and behind-the-scenes featurettes between programs. This relieves HBO from some pressures to tone down controversial aspects of its programs, and allows for explicit content to air, such as graphic violence, sexual situations and profanity."
