"Culture jamming," a term I have popularized by articles in The New York Times and Adbusters, might best be defined as media hacking, information warfare, terror-art, and guerrilla semiotics, all in one. Billboard bandits, pirate TV and radio broadcasters, media hoaxers, and other vernacular media wrenchers who intrude on the intruders, investing ads, newscasts, and other media artifacts with subversive meanings are all culture jammers.

"Culture Jamming" sticks where rational discourse slides off. It is, simply, the viral introduction of radical ideas. It is viral in that it uses the enemy's own resources to replicate iteself -- corporate logos, marketing psychology, clean typography, "adspeak". It is radical because--ideally--the message, once deciphered, causes damage to blind belief. Fake ads, fake newspaper articles, parodies, pastiche. The best CJ is totally unexpected, surprising, shocking in its implications.
