From TVTV’s iconoclastic television broadcast from the floor of the 1972 Republican Convention to Gregory Green’s recent pirate-radio-station installations, artists have frequently intervened into systems of broadcasting in order to challenge the influence and power of TV and radio. Broadcast examines these often courageous interventions, showing how artists since the late 1960s have engaged with or inserted themselves into official TV and radio channels, often fruitfully exploiting the conditions of live broadcasting–whether by appropriating news reporting, intervening in live programs or creating extensive broadcasts themselves. It is the first book of its kind to address this provocative and exciting body of work, published on the occasion of the exhibition at Baltimore’s Contemporary Museum of Art, and it also includes an illustrated and annotated timeline that traces moments in television and radio history related to developments in contemporary art. This timeline serves as an addendum to the catalogue’s texts, offering a place for any details, events and facts that lie outside the particular scope of each essay. Artists in the exhibition include Dara Birnbaum, Chris Burden, Gregory Green, Christian Jankowski, Inigo Manglano-Ovalle, Antonio Muntadas, Nam June Paik, TVTV (Top Value Television) and Siebren Versteeg.
