ABOUT THE SHOW: Calling All Cars was one the earliest police shows to air on the radio. The format was similar to Dragnet in many ways. It was based in California, it dramatized true crime stories, and it included interviews with real officers. Calling All Cars was never broadcast nationwide. It was only heard by listeners in areas where Rio Grande Gasoline was sold. Rio Grande sponsored the program through its six year run and used the air-time to convince listeners that by using its "cracked" gasoline their car would run like a police car – advice which I am sure was taken on board by every crook in the vicinity. Stars Charles Bickford amongst others. Created from introductions by officers of the Los Angeles and other police departments. Dramatizations of true crime stories were later done by Jack Webb and others in shows like Dragnet.
