This is the first in a series of compilations designed to give a glimpse into the kind of radio programs being broadcast at a specific time. This compilation covers the early 1930s, though there aren't as many extant broadcasts as later years, but I think this is still a pretty solid sampling.

You can listen to thousands of Old Time Radio programs provided by the Old Time Radio Researchers Group: https://archive.org/details/@otrrarchive?sort=-week
