About the podcast

A new episode daily. CBS Radio Mystery Theater was a noteworthy attempt to revive in American radio dramas like Inner Sanctum (1941-1952) and Suspense (1942-1962). Radio dramas were widely considered "dead" 12 years prior to this series. CBS Radio Mystery Theater, or simply Mystery Theater, was created by Inner Sanctum creator Himan Brown and ran on CBS from 1974-1982. The show, much like older radio dramas, was introduced by a host (in this case E.G. Marshall), who steers us through the creaking door to start the episode. Many voices from the golden age of radio were featured, including Richard Widmark, Bret Morrison and Agnes Moorehead.
