“Culture jamming is an intriguing form of political communication that has emerged in response to the commercial isolation of public life.
Practitioners of culture jamming argue that culture, politics, and social values have been bent by saturated commercial environments, from corporate logos on sports facilities, to television content designed solely to deliver targeted audiences to producers and sponsors.
Culture jamming presents a variety of interesting communication strategies that play with the branded images and icons of consumer culture to make consumers aware of surrounding problems and diverse cultural experiences that warrant their attention. ”
