Audiences Unlimited helps fill seats for television programs (and sometimes for televised award shows). There's no charge, but tickets are distributed on a first-come, first-served basis. Shows that may be taping or filming include Will & Grace and Everybody Loves Raymond. Tickets are received by mail or reserved over the Internet only. Note: you must be 16 or older to attend a television taping. For a schedule, send a self-addressed, stamped envelope to Audiences Unlimited a few weeks prior to your visit. Note that most network comedies are on hiatus from April through July.
