On the Air is a 1937 educational film about radio broadcasting from the Jam Handy Organization. It opens with a studio radio performance by celebrated violinist David Rubinoff and his orchestra, all dressed in formal attire, showing the musicians but also some of the production details — hand signals from the booth, and adjustments of various dials and knobs. And then we’re off on a technical explanation of sound waves, radio signals, amplification and transmission, showing how the sound from the studio is makes it way into the living rooms and automobiles of America.
This ten minute black-and-white film was made for the Chevrolet Division, General Motors Corporation, and is one of several Jam Handy productions from the Prelinger Archives available through the Internet Archive.
