It is increasingly in the media, but what exactly is culture jamming and how does it work?Culture jamming is a form of protest in which advertisements and other media messages are re-arranged or parodied in humorous or disturbing ways. The term covers a range of practices, including sabotaging billboards, spoofing well-known ads, and hoaxing the mainstream media.The purpose of culture jamming is to expose the reality behind corporate spin and to reclaim the media and public spaces from the influence of powerful corporations. Just as radio ‘jammers’ interrupt broadcasts with their own messages, culture jammers disrupt the everyday flow of the mainstream media by proposing alternative meanings.The term culture jamming was first coined in the mid-1980s by members of Negativland: an experimental band from San Francisco.
