Talk radio
Talk radio is a radio format built around spoken-word programming, including interviews, commentary, listener call-ins, and discussion.
Radio phone-in: A radio program segment in which listeners call a station to speak on air. Phone-ins turn talk radio into a live exchange between hosts and listeners.
Radio broadcasting: The transmission of audio programs by radio waves to receivers over a broad area. Talk radio emerged as a programming format within the wider institution of radio broadcasting.
Political talk radio: Talk-radio programming focused on political news, arguments, and public affairs. Political commentary is one of the most prominent and influential talk-radio genres.
Music radio: Radio programming in which recorded or live music is the principal content. Music radio centers listening on songs, while talk radio centers it on speech.
Fairness Doctrine: A former United States broadcast policy requiring stations to present contrasting views on controversial public issues. The policy shaped how American broadcasters handled political commentary and controversial talk.
Radio host: A presenter who guides a radio program and speaks to its audience. Hosts set the pace, frame topics, and manage callers and guests.
Amos 'n' Andy: An American radio comedy series that became one of the medium's most popular early programs. Its serialized dialogue demonstrated how spoken entertainment could attract mass radio audiences.
Sports talk radio: Radio programming devoted to sports news, analysis, and discussion with callers or guests. It applies talk radio's recurring discussion format to games, teams, and athletes.
Podcast: A digital audio program distributed online, typically as episodes available on demand. Podcasts share talk radio's spoken content but are usually distributed for on-demand listening.
