How to box with the shadows ? "Jamming" is slang for the illegal practice of interrupting radio broadcasts or conversations between fellow hams with lip farts, obscenities, and other equally jejune hijinx. The term "cultural jamming" was first used by the collage band Negativland to describe media sabotage. "The studio for the cultural jammer is the world at large", a mock-serious bandmember observes. An elastic category, culture jamming accommodates a multitude of subcultural practices in which tales told for mass consumption are perversely reworked. Transmission jamming, outlaw computer hacking, pirate TV and radio broadcasting ; camcorder countersurveillance - slashing derives from the pornographic K/S - short for Kirk/Spock - stories written by female Star Trek fans and published in underground fanzines - are all modus operandi for the culture jammer.
