I liked some of the comedies.
My Friend Irma
The one with Eve Arden playing a sarcastic high school teacher.
The Life of Riley
Fibber McGee & Molly
As a young child I loved the Lone Ranger, and I distinctly remember the terrible moment when it dawned on me that Kemosabe wasn't real, but just a character in a radio story. Finding out about Santa Claus had nothing on that!
Saturday morning had one kid-appropriate radio drama after another, and I would listen to them while doing the Saturday chore, cleaning my room.
There was one that dramatized fairy tales, and I can still remember the theme song!
To this day I prefer radio to TV, after all you can get so much done while listening, and I keep NPR on all day long.
