Talk radio is a radio format containing discussion about topical issues and consisting entirely or almost entirely of original spoken word content rather than outside music. They may feature monologues, dialogues between the hosts, interviews with guests, and/or listener participation which may be live conversations between the host and listeners who "call in" or via voice mail. Listener contributions are usually screened by a show's producers to maximize audience interest and, in the case of commercial talk radio, to attract advertisers.
