Blipvert

A blipvert is a very brief television advertisement, lasting one second. The word is a portmanteau of blip, a brief sound, and advertisement.

The term and concept were used in the 1985 film Max Headroom: 20 Minutes into the Future and in Blipverts, 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 the channel-switching that may occur during standard-length commercials, but they had the side-effect of making some viewers explode. They were invented as a MacGuffin to drive the plot.
