The CBS Radio Mystery Theater (or CBSRMT) was an ambitious and sustained attempt to revive the great drama of old-time radio in the 1970s. Created by Himan Brown (who had by then become a radio legend due to his work on Inner Sanctum Mysteries and other shows dating back to the 1930s), and aired on affiliate stations across the CBS Radio network, the series began its long run on January 6, 1974. The final episode ran on December 31, 1982. The show was broadcast nightly and ran for one hour, including commercials. Typically, a week consisted of three to four new episodes, with the remainder of the week filled out with reruns. There were a total of 1399 original episodes broadcast. The total number of broadcasts, including reruns, was 2969. The late E.G. Marshall hosted the program every year but the final one, when actress Tammy Grimes took over. Each episode began with the ominous sound of a creaking door, slowly opening to invite listeners in for the evening's adventure. At the end of each show, the door would swing shut, with Marshall signing off, "Until next time, pleasant...dreams?"
