Apparently radio was once controlled by the mob:

From the late 1970s through 1986, radio was controlled by the mob, and you had a lot of people getting hundred dollar bills in record sleeves or cocaine hidden inside cassette tapes.... Yes, the Gambino family. There's a great book on payola in the 1980s by Fredric Dannen called "Hit Men." Basically, there was a cartel of consultants called "The Network" that bribed programmers and was extorting money from record labels. If you didn't pay their billings they'd blacklist your artists.Most famously they had Pink Floyd kicked off the LA airwaves during an extremely successful concert tour as retaliation against their label.This cartel was connected to Piney Armone, a Gambino underboss.
