Payola, in the American music inustry, is the illegal practice of payment or other inducement by record companies for the broadcast of recordings on music radio, in which the song is presented as being part of the normal day's broadcast. Under US law, 47 U.S.C. § 317, a radio station can play a specific song in exchange for money, but this must be disclosed on the air as being sponsored airtime, and that play of the song should not be counted as a "regular airplay." The term has come to refer to any secret payment made to cast a product in a positive light (such as obtaining positive reviews).
