Playbill is a monthly U.S. magazine for theatregoers. Although there is a subscription issue available for home delivery, most copies of Playbill are printed for particular productions and distributed at the door as the show's program.
Playbill was first printed in 1884 for a single theatre on 21st Street in New York City. The magazine is now used at nearly every Broadway theatre, as well as many Off-Broadway productions. Outside New York City, Playbill is used at theatres throughout the United States. Circulation as of September 2012 was 4,073,680. Source
