A promotional recording, or promo, is an audio or video recording distributed for free, usually in order to promote a recording that is or soon will be commercially available. Promos are normally sent directly to broadcasters, such as music radio and television stations, and to tastemakers, such as DJs and music journalists, in advance of the release of commercial editions, in the hope that airplay, reviews, and other forms of exposure will result and stimulate the public's interest in the commercial release.
