NewsRadio has referenced the movie a couple of times:
In the first season episode "Big Day", Dave learns that every year, Jimmy gives out bonuses of $400 to everyone except for one person who will get $3,000, and one person who gets nothing, or as Jimmy calls it, "The Shaft". Everyone else assumes Matthew will be the one who gets nothing, leading to this exchange.
Bill: Joe, who's the black undercover dick who's a sex machine with all the chicks? Joe: Why, I believe that would be Shaft, Bill. Bill: Mmm-hmm. And who's the cat who won't cop out when there's danger all about? Joe: Once again, Bill, you are referring to Shaft. You know, they say Shaft is one bad mutha- Matthew: Just shut up, you guys. Jimmy: What're you guys doing? Bill: We're just talking about Shaft. Jimmy: I can dig it.
In the third season episode "Complaint Box", Dave puts out a complaint box for others in the office, and naturally, one of the complaints contains the lyrics of the theme song (to which everyone else yells out, "Shaft!").
Sesame Street: "Cookie Disco" is a parody of the theme.
Veronica Mars: In the first season episode "Clash of the Tritons", Wallace claims he confronted a kid about a fake ID like Shaft, to which Veronica replies, "Shut your mouth!"
The Wire: In the third season premiere episode "Time After Time", when Carver and Herc drive after some drug dealers, Herc puts the theme from Shaft on in the car.
The Simpsons: In "One Fish, Two Fish, Blowfish, Blue Fish", Bart and Lisa sing the movie's theme song on a Japanese restaurant's karaoke stage. Reportedly, the network initially refused to air the scene as they thought it was inappropriate for the show's timeslot. The producers had to track down footage of the song being performed at the Academy Awards to prove it had already aired in primetime without issue.
