aka Old time radio? When I was a kid we used to receive AM radio signals at night time from high watt transmitters in Chicago about 600 miles away. One of my favorite radio shows was CBS Radio Mystery Theater that aired from 1974 to 1982 and was an attempted revival of the older years of OTR.
The sad part was CBS didnt think it was anything special so they never put any of them to master tapes so the only accessable copies are the ones that people taped from the radio. Remarkably people figured out it was special enough that all episodes were preserved in old audio tapes, some even with the old commercials that ran between the three acts of the story.
