Behind Your Radio Dial

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.

Cast: Ben Grauer, Arturo Toscanini, H.V. Kaltenborn, Fred Allen
