In radio broadcasting, stunting occurs when a station abruptly airs content that is seemingly uncharacteristic compared to what they normally play. The tactic is commonly used when a station is about to undergo a major change (such as a change in format, branding, frequency, ownership or management, or even the acquisition of a high-profile program or personality), or simply as a prank on listeners and rival broadcasters. Either way, stunting is intended as a way to generate a greater amount of media publicity and audience attention to the station, by virtue of its shock value, than a straightforward format change could provide. Depending on the station's situation and its management's preference, stunt formats can last anywhere from a few minutes to several weeks before the permanent change is launched.
A station may stunt by repeating the same song or songs over and over on a continuous loop.
In a prelude to a format flip, a series of audio clips and sound effects centered around a certain theme may be played. Known as a sound collage, the theme under which these bits of audio fall may or may not have something to do with the previous and/or new format.
When changing formats, a station may be upfront about the nature of the new format by using a limited playlist of songs or highlights of the new format, an approach intended to preview what to expect after the format change takes place.
Occasionally a station dropping an old format will stunt with a temporary transitional format, one intended to tease not so much the listener but competing stations who are not privy to the station's new plans. The fake format, more often than not, is only intended as a transition to a new format or existing format adjustment. A similar, but smaller, effect can be produced by registering numerous domain names suggesting various formats, in an effort to throw off "net gnomes" and generate buzz.
A station may stunt by temporarily formatting a series of novelty songs, a song style that usually wouldn't support itself as a stand-alone commercial radio format.
A station may mix musical selections from both its old and new formats for a period of time. This smooth transition works best if the formats have little to no normal overlap in their playlists, such as a shift from country music to rhythmic contemporary or alternative rock; it may not be as effective or obvious if the transition is from, for example, modern rock to alternative rock. This type of stunting does not occur as often as other forms, as the approach does not increase the shock and anticipation value as much as with the other forms.
