Sears Radio Theater was a radio drama anthology series which ran weeknights on CBS Radio in 1979, sponsored by the Sears chain. Often paired with The CBS Radio Mystery Theater during its first season, the program offered a different genre of drama for each day's broadcast. In January 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.
