 the early 80s it was kind of like the renaissance of or a rebirth of old-time radio shows which i really liked and they're a lot more obviously contemporary than some of these other ones from the 40s and 50s but they also had i think almost 1400 episodes before they folded in the early 80s that's true and i can't remember the gentleman's name that created inner sanctum but i believe that he was producing that show in the 70s as well too
