An FCC spokesman confirmed to The Post on Monday that the commission was not launching an investigation.

Even if there was one, the “Late Show With Stephen Colbert” airs, well, late enough that it is exempt from the FCC’s policies on profanity and indecency. The FCC defines indecent content as that which “portrays sexual or excretory organs or activities in a way that does not meet the three-prong test for obscenity.” Profane content “includes ‘grossly offensive’ language that is considered a public nuisance,” according to the commission.

However, these rules don’t apply to broadcast TV and radio shows that fall into a “safe harbor” period — airing between 10 p.m. and 6 a.m., ostensibly when children are not watching or listening. Colbert’s show airs at 11:35 p.m. Eastern [and, to my knowledge, also airs after 10 p.m. in other time zones -EV].

Obscene content, on the other hand, is the most serious of the three FCC designations and prohibited by law no matter the time of day. Even then, “there is ZERO chance” that Colbert’s comments would meet the obscenity test, Schwartzman said.
