Person who plays recorded music on radio or television or at a nightclub or other live venue.
Disc jockey programs became the economic base of many radio stations in the U.S. after World War II. The format generally involves one person, the disc jockey, introducing and playing phonograph records and chatting informally, usually extemporaneously, in the intervals. Because popular DJs are in a position to influence public tastes, record companies have sometimes attempted to bribe them with money and gifts, known as "payola."
