What radio drama anthology series, known for its twist endings, ran from 1974 to 1982 on CBS?

The radio drama anthology series that captivated audiences with its suspenseful narratives and signature twist endings, airing on CBS from 1974 to 1982, was the CBS Radio Mystery Theater. This iconic program marked a significant effort to revive the "golden age" of radio drama during an era largely dominated by television.

Each episode of the CBS Radio Mystery Theater presented a self-contained story, delving into genres like mystery, horror, and psychological thrillers. A hallmark of the show was its unexpected conclusions, which often left listeners pondering long after the final credits. This format, combined with a strong emphasis on atmospheric sound effects and compelling voice acting, created an immersive experience that stood out during its nine-year run.

The series was the brainchild of legendary radio producer Himan Brown, who brought a wealth of experience from earlier radio hits like "Inner Sanctum Mysteries." Brown's distinctive touch included the ominous sound of a creaking door that opened and closed each episode, a familiar element from his past work. Hosted by the distinguished E.G. Marshall for most of its run, with Tammy Grimes taking over for the final year, the CBS Radio Mystery Theater produced an impressive 1,399 original episodes, cementing its place as a memorable entry in broadcasting history.
