term for an advertising message that is broadcast on television or radio. An advertising message in print is called an advertisement. A broadcast message is structured by time rather than by space (as is an advertisement), and so must be creatively designed around words, sound, and music for radio, plus sight and motion for television.

Commercials are produced on film or videotape, which is then duplicated so that copies may be distributed to the various stations where they will be aired.
