FCC Guidelines
According to the Federal Communications Commission, federal law prohibits obscene, indecent and profane content from being broadcast on the radio.
Deciding what’s obscene, indecent or profane
Each type of content has a distinct definition:
Obscene content does not have protection by the First Amendment. For content to be ruled obscene, it must meet a three-pronged test established by the Supreme Court: It must appeal to an average person’s prurient interest; depict or describe sexual conduct in a “patently offensive” way; and, taken as a whole, lack serious literary, artistic, political or scientific value.
Indecent content portrays sexual or excretory organs or activities in a way that is patently offensive but does not meet the three-prong test for obscenity.
Profane content includes “grossly offensive” language that is considered a public nuisance.
Factors in determining how FCC rules apply include the specific nature of the content, the time of day it was broadcast and the context in which the broadcast took place.
