"One of the earliest and most important of these groups was Top Value Television (TVTV), a collective founded in San Francisco which was active from 1972 to 1979. During that time, they produced numerous independent documentaries, often by bringing their cameras to major events. TVTV’s vast catalog of raw footage and other materials has long been kept in the UC Berkeley Art Museum and Pacific Film Archive (BAMPFA)." https://hyperallergic.com/584119/bampfa-tvtv-online-archive/
