Blipvert

A blipvert is a very brief television advertisement, that lasts just one or several seconds. The term "blipvert" was coined by George Stone. The word is a portmanteau of blip, a brief sound, and advert, the British abbreviation for advertisement.

The term and concept were popularized in the 1985 film Max Headroom: 20 Minutes into the Future and the first episode of the 1987 science fiction television show Max Headroom. In the film and TV show, "blipverts" were new high-speed, concentrated, high-intensity television commercials lasting about three seconds. Their purpose was to prevent channel-switching during standard-length commercials.
