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.

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.
