Culture jamming, a tactic used by many consumer social movements, is a mechanism in which an activist or activist group attempts to disrupt or subvert mainstream cultural institutions including corporate advertising. Culture jamming is often seen as a form of subvertising. Many culture jams are simply aimed at exposing questionable political assumptions behind commercial culture so that people can momentarily consider the branded environment in which they live. Culture jams re-figure logos, fashion statements, and product images to challenge the idea of what's cool, along with assumptions about the personal freedoms of consumption.
