of South Park, "It Hits the Fan" (original airdate 20 June 2001), parodied the hype over the Chicago Hope episode. In it, "shit" is used 162 times, and a counter in the corner of the screen tallies the repetitions (excluding the 38 instances of the word's use in written forms, the raising the total to an even 200). South Park airs on American cable networks, which are outside the FCC's regulatory jurisdiction and whose censorship of vulgar dialogue is at the discretion of the cable operators. Since that episode, the word (as well as many on-screen depictions of feces, as well as defecation) has become a mainstay of South Park. Various episodes also feature a character, Mr. Hankey, who is a sentient turd.

The 1973 Pink Floyd song "Money" from the album The Dark Side of the Moon contains the line "Don't give me that do goody good bullshit", and has frequently been broadcast unedited on US radio. The 1980 hit album Hi Infidelity by REO Speedwagon contained the song "Tough Guys" which had the line "she thinks they're full of shit", that was played on broadcast radio. On 3 December 1994, Green Day performed "Geek Stink Breath", on Saturday Night Live, shit was not edited from tape delay live broadcast. The band did not appear on the show again until 9 April 2005. Some notable instances of censorship of the word from broadcast television and radio include: Steve Miller's "Jet Airliner". Although radio stations have sometimes played
