The majority of programming syndicated by iHeartMedia is distributed through its subsidiary, Premiere Networks, owned by the company since 1999 and purchased by antecedent Jacor in 1997. However, several music and talk shows originated on iHeartMedia-owned stations are syndicated by those stations without the assistance of Premiere, or via a third-party distributor. Talk shows of this type are generally broadcast through Orbital Media Networks, Inc., formerly Clear Channel Satellite Services. Music programs of this type, including music scheduling and voice-tracking, are distributed through an intranet service known as "Premium Choice".
