Global Groove was a collaborative piece by Nam June Paik and John Godfrey. Paik, amongst other artists who shared the same vision in the 1960s, saw the potential in the television beyond it being a one-sided medium to present programs and commercials. Instead, he saw it more as a place to facilitate a free flow of information exchange. He wanted to strip away the limitations from copyright system and network restrictions and bring in a new TV culture where information could be accessed inexpensively and conveniently. The full length of the piece ran 28 minutes and was first broadcasted in January 30, 1974 on WNET.

Familiar radio voice Ben Grauer leads the viewer on a behind the scenes tour of the National Broadcasting Company studios -- both radio and television -- in Rockefeller Center and Hollywood. The original 25-minute film previewed by network execs and affiliates in the fall of 1948 was cut down to 20 minutes before its first broadcast, reportedly to excise high-profile stars and programs such as Amos 'n' Andy, Jack Benny, and Edgar Bergen that had since left NBC for other networks.
