Nam June Paik, the father of video art, celebrated in new documentary 'Moon is the Oldest TV'

Nam June Paik's been called the "father of video art." And he was — but he was so much more.

He held PhDs in Renaissance music and philosophy, spoke a dozen languages, and headed a 1960s avant-guard art movement called Fluxus that counted Yoko Ono among its members. His early art was excoriated by art critics, but his later work — from an installation featuring a Buddha propped in front of a television to his cutting-edge work with video and music — was beloved. Some called it visionary.

Sixteen years after his death, a new documentary, "Moon is the Oldest TV," examines his life through newsreels, interviews, video clips and recordings. Host Robin Young talks to filmmaker Amanda Kim about Paik's life.
