Mick Hartney writes a short survey on video art in a Grove Art dictionary on 20th century Western art styles and movements. The term 'video art' describes art that uses both the apparatus and processes of television and video. The origin of the art form can be traced back to the works in 1959 by video artists Wolf Vostell and Nam June Paik. Nowadays, video art has evolved beyond the gallery context and become part of an increasingly elaborate network of electronic communication.
