You haven't been reading. The contract specifically referances FCC violations as a breech of contract. That directly involves FCC regulations.
Yes dear, I’ve been reading (although granted I haven’t seen the contract). You clearly misunderstood the point of my post, which is that CBS (and I’ll add MSNBC as well) did not terminate Imus because he violated FCC regulations (or any other aspect of his contract). Even if he did so, that was not the reason for his firing. His employers pulled the plug because of pressure not from the FCC, but from hypocritical, hate-mongering racists Al Sharpton and Jesse Jackson, as well as the wussified corporate sponsors who caved into their hissy fits. We know this because one or both companies announced immediately after the firestorm broke that in light of his apology, a two-week suspension would suffice.
