The head of PBS is firing back at the FCC over the agency’s new no-tolerance policy governing profanity on television, saying that it is “important for public broadcasting not to just roll over, but to be very clear that in order to tell some stories, we may need to use language that, at the moment, the FCC is not sure that they feel is appropriate for broadcast television.” PBS is worried that it will have to cut or digitally obscure certain words in the latest Ken Burns documentary, focusing on World War II, in order to avoid heavy FCC fines.
