“The New Television Workshop originated at WGBH, a public broadcasting station in Boston, Massachusetts, in 1974 to support the creation and development of experimental video art. This experimental programming included dance, drama, music, performance and visual arts on video and
film. As early as 1968, WGBH was committed to the development of video art through residency programs, with artists such as Nam June Paik. Many of these early works (pre-1974) were broadcast both locally and nationally.” [1]
