guerrilla television

n. A form of television proposed by former Time-Life correspondent Michael Shamberg to describe how the counter-culture movement of the late 1960s and early 1970s should use communication technology to get its message to the public, because despite its strategies and tactics similar to warfare, guerrilla television is non-violent.
