Radio comedy, or comedic radio programming, is a radio broadcast that may involve sitcom elements, sketches and various types of comedy found on other media. It may also include more surreal or fantastic elements, as these can be conveyed on a small budget with just a few sound effects or some simple dialogue.
Radio comedy in the United States began when Raymond Knight launched The Cuckoo Hour on NBC in 1929, along with the 1931 network debut of Stoopnagle and Budd on CBS. Comedians such as Fred Allen, Jack Benny, Judy Canova, Bob Hope and Red Skelton were top-rated in the decades that followed. Even after the big name comedians moved to television, radio comedy continued, notably from Bob and Ray, The Firesign Theatre and segments heard on NBC's Monitor.
Although traditional comedy was once a significant part of American broadcast radio programming, it is now mainly found in the archives of Old Time Radio enthusiasts and on the Internet streaming of comedy recordings. The majority of mainstream radio comedy now consists of personality-driven shows hosted by talk-radio hosts such as Howard Stern or comedic duos such as Armstrong & Getty and Bob & Tom. Exceptions to this are WSRN's "Audience of Two", Garrison Keillor's work on Minnesota Public Radio: A Prairie Home Companion and Comedy College, and NPR's Car Talk, a comedy show thinly disguised as car advice, and Wait Wait... Don't Tell Me!. Shows featuring comedic music are also popular; one of the better known national comedy music programs is the long-running weekly program hosted by Dr. Demento, and several other local stations (mostly college radio, freeform and eclectic formats) have similar programs. Several networks program 24 hours a day of stand-up comedy routines; several channels on the Sirius XM Radio platforms focus on this format, as does the terrestrial All Comedy Radio network. Rock music stations often play bits of stand-up comedy within the bounds of their regular formats, usually under the banner of a "five o'clock funnies" feature.
