Honestly I don’t know much about the history of this broadcast. It’s one of the hard ones to find but I do know that it aired in January through February of 1946 and came in 13 parts. I enjoyed it and we will have it in three parts. Please enjoy our Sunday routine of The Adventures of Superman “Is There Another?”
The serial came to radio as a syndicated show on New York City’s WOR on February 12, 1940. On Mutual, it was broadcast from August 31, 1942, to February 4, 1949, as a 15-minute serial, running three or, usually, five times a week. From February 7 to June 24, 1949 it ran as a thrice-weekly half-hour show. The series shifted to ABC Saturday evenings on October 29, 1949, and then returned to afternoons, twice-a-week on June 5, 1950, continuing on ABC until March 1, 1951. In all, 2088 original episodes of The Adventures of Superman were aired on American radio.
This will run you about 1 hour.
