I love old time radio. The shows from the 30s, 40s, and 50s. It doesn't matter which genre. I love them all. An easy way to sample some old time radio is at
PodcastAlley. They have quite a variety of podcasts to choose from so browse and sample.

I have serveral hundred old time radio shows in my collection and I'm always searching to complete or add to my titles.

Here's a list of websites on Google that also have shows to download and stream.
