Premiering on January 6, 1974, the CBS Radio Mystery Theater was a notable attempt to revive the tradition of radio thrillers like Suspense (1942-1962) and Inner Sanctum Mysteries (1941-52). Created by Inner Sanctum producer Himan Brown, the CBS Radio Mystery Theater featured many voices from the golden age of radio, including Agnes Moorehead, Les Tremayne, Santos Ortega, Bret Morrison, and Mercedes McCambridge. E. G. Marshall was its first host. The series ended on December 31, 1982.
