“The Yes Men are among the most visible and effective activist-artists of our time, reaching countless people through websites, newspapers, and television broadcasts. Over the past decade they have fearlessly taken on the world’s biggest corporations and bureaucracies.

The imitation of advertisements and modification of logos are popular tactics used by jammers to disrupt the intended message of marketers. In light of this, culture jamming is sometimes mistaken for vandalism.

The term ‘culture jamming’ was first coined in 1984 by San Francisco-based collage band Negativland.
