Ever since the FCC “decency” crackdown began, US television networks have been slamming disclaimers on any program containing even mildly profane content or innuendo. Even PBS’s award-winning documentary series, “Frontline,” has run with disclaimers about language and content. What’s the point? Well, obviously, the disclaimers give the networks a bit of plausible deniability if the FCC comes calling, but more importantly, studies have consistently shown that viewers want racy, controversial programming, and the disclaimer might even cause a few pairs of eyes to stay tuned.
