Radio Theater w/ foley and music is, for me, one the most entertaining forms of storytelling. Because of the popularity of podcasts, it's enjoying a revival. I still really prefer old broadcasts because the old voices, accents, organs, and ancient commercials.
Recently I've really been listening to Dimension X (1950/51), the second sci-fi show on the air and adapted from popular short stories. My favorite so far is episode 14: Mars is Heaven.
Anybody else into radio plays? Any favorite shows? Favorite episodes? Old or new.
