Watch HDToday. Produced by WGBH-TV in Boston, the Medium Is the Medium is one of the earliest and most prescient examples of the collaboration between public television and the emerging field of video art in the U.S. WGBH commissioned artists — Allan Kaprow, Nam June Paik, Otto Piene, James Seawright, Thomas Tadlock and Aldo Tambellini — to create original works for broadcast television. Their works explored the parameters of the new medium, from image processing and interactivity to video dance and sculpture.
