Nightwatch took the listeners for a prowl car ride along with the Culver City, California Police Department. The show was created and hosted by Donn Reid. The host narrated while he rode along with the police on various calls, which could include burglaries, attempted murders, and tracking down escapees. The show was a predecessor to today's “reality” shows, but better. The show ran from 1954 to 1955 on CBS.
