In Feedback, David Joselit describes the privatized public sphere of television and recounts the tactics developed by artists and media activists in the 1960s and 1970s to break open its closed circuit.
The figures whose work Joselit examines—among them Nam June Paik, Dan Graham, Joan Jonas, Abbie Hoffman, Andy Warhol, and Melvin Van Peebles—staged political interventions within television's closed circuit. Joselit identifies three kinds of image-events: feedback, which can be both disabling noise and rational response—as when Abbie Hoffman hijacked television time for the Yippies with flamboyant stunts directed to the media; the image-virus, which proliferates parasitically, invading, transforming, and even blocking systems—as in Nam June Paik's synthesized videotapes and installations; and the avatar, a quasi-fictional form of identity available to anyone, which can function as a political actor—as in Melvin Van Peebles's invention of Sweet Sweetback, an African-American hero who appealed to a broad audience and influenced styles of Black Power activism. These strategies, writes Joselit, remain valuable today in a world where the overlapping information circuits of television and the Internet offer different opportunities for democratic participation.
