Talk radio

Talk radio is a radio format containing discussion about topical issues. Most shows are regularly hosted by a single individual, and often feature interviews with a number of different guests. Talk radio typically includes an element of listener participation, usually by broadcasting live conversations between the host and listeners who "call in" (usually via telephone) to the show. Listener contributions are usually screened by a show's producer(s) in order to maximize audience interest and, in the case of commercial talk radio, attract advertisers. Generally, the shows are organized into segments, each separated by a pause for advertisements; however, in public or non-commercial radio, music is sometimes played in place of commercials to separate the program segments. Variations of talk radio include conservative talk, hot talk, liberal talk (increasingly known as Progressive talk) and sports talk.

While talk radio has historically been associated with broadcast radio, starting around 2005 the technology for Internet-based talk-radio shows became cost effective in the form of live internet website streaming and podcasts. Now, it is possible for an individual to use a variety of services to host an Internet-based talk-radio show without carriage by a traditional radio station. In addition TV programming from talk and news outlets such as BBC, CNN, Bloomberg and Fox are now often available expanding the world of talk radio further. Talk radio listening is now enjoyed not only on radios, but a wide variety of other devices and services including PCs using iTunes, station directories such as TuneIn, show directory smartphones with apps such as Stitcher and time shifting services like DAR.fm.
