In case you haven't been following all the collections at archive.org, here's an article that showcases some amazing science fiction episodes from the early 1950's Dimension X radio show. Fifty half hour shows are available at the archive.org site which should be a good TV replacement for a week or two.
From the site:
Dimension X made its mark by adapting short stories by acknowledged masters of the craft: Isaac Asimov, Ray Bradbury, Robert Heinlein, and even a non-genre-bound literary mind like Kurt Vonnegut. All of these world-creators knew well the value of imagination, and radio, in its way, stood then and remains today the most evocative, imagination-driven medium of them all.

About 10 years ago I subscribed to live365, and ended up mostly listening to those old-time radio shows. I especially liked the Science Fiction ones.
I came. I saw. I forgot why I came.
