When a song is cleared for usage on a TV show, historically to save money, the clearance typically applies only to television airings of the show in question. Thus, when the show is considered for DVD distribution to the home video market, the rights to the song must be renegotiated in order for the song in question to be included on the DVD. Most producers/production companies now include the rights for DVDs or "all media now known or hereafter devised," which assures production companies of the right to re-release without incurring additional licensing fees.
