Calling All Cars


Calling All Cars was a radio show that was first broadcast in 1933. The image above shows a panel from a 1939 road map distributed by the show’s sponsor.

“Every week a dramatization based on an actual police case file was… introduced by a real police officer… Sponsored by the Rio Grande Oil Company… [it] aired only along the West Coast, restricted to only the territory where the sponsor’s product was distributed… [T]here was evidence that the weekly detective program was the most popular originating from the West Coast facilities of CBS… Commercially, the program was a huge success. In 1938 Parker Brothers issued a board game based on the radio program…

Calling All Cars expanded to the Midwest beginning in January of 1939…”
