Some fodder for this thread:
The FCC definition of indecency:
“Language or material that, in context, depicts or describes, in terms patently offensive as measured by contemporary community standards for the broadcast medium, sexual or excretory activities or organs.”
If it fits this definition and is indecent, then it's subject to "channeling" or "safe harbor laws." This means if it's broadcast on network televition between 6am and 10pm, it's subject to indecency prosecution. (Cable TV isn't subject to these laws).
