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.

A podcast is a program made available in digital format for download over the Internet. For example, an episodic series of digital audio files that users can download to a personal device to listen to at a time of their choosing. Podcasts are primarily an audio medium, but some distribute video, either as their primary content or as a supplement to audio.
