Sears Radio Theater was a radio drama anthology series that presented a different genre of drama for each day's broadcast. The series featured a variety of themes, such as "Western Night," "Comedy Night," "Mystery Night," "Love and Hate Night," and "Adventure Night." Each of these themes was hosted by a different celebrity, including Lorne Greene, Andy Griffith, Vincent Price, Cicely Tyson, Richard Widmark, Howard Duff, and Leonard Nimoy. The show included many actors from the Golden Age of Radio, and the program was produced and directed by Fletcher Markle and Elliott Lewis. The theme music for the show was composed and conducted by Nelson Riddle. Sears Radio Theater was praised for its ambitious attempt to reinvigorate radio drama and was broadcast in stereo.

The show initially aired on CBS Radio in 1979 and was sponsored by the Sears chain. In 1980, the program moved to the Mutual Broadcasting System and became the Mutual Radio Theater. The Mutual series broadcast repeats from the CBS run until September 1980, when a short season of new dramas was presented. Sears continued as a sponsor during the Mutual run. The series ended as Mutual's final radio drama series but continued to broadcast repeats of the program, along with a few previously unaired episodes, until December 1981.
