Old Time Radio (OTR) - amazing to learn history by listening to the radio programs of the day
On an app called Podcast Addict there are old time radio channels available. They even do old comedy and sci-fi shows.
I like falling asleep to them at night.
YouTube has a ton of them, as does Archive.org. Old Gameshows from the 50’s are a great time too.

A great way to get started IMO is to listing to Command Performance. During WWII, all of Hollywood came together to put together radio shows that were recorded and send to radio stations throughout the world. They were a combination of Hollywood stars, comics and great musicians coming together - here’s a link to over 200 episodes - https://archive.org/details/command-performance-1948-12-25-xx-christmas-1948
