Radio sure didn't last long. I'm probably one of the few, my age (mid 20's), who considers this medium most special and credible--at least I can recognize it beyond the FM dial. Radio, specifically dramatized radio, was survived by TV, therefore it never was able to push the envelope or so to speak. It never grew out of infancy. It never had the chance. Many consider Orson Welles' War Of The Worlds the tip of the iceburg, but even then it never got an audience as grand as TV then and now.
I will be updating this page with my radio collection list shortly. Please bear with me, there's a lot of data entry up ahead.
If you're unfortunate to listen Garrison Keller radio shows you probably haven't heard the full potential of radio drama. Incidentally, my prayers have been answered as radio stations around the world air new or contemporary shows, albeit they are not as enjoyable to me personally as vintage radio. Imagination Theatre is the title of a new series of radio shows I have had the pleasure to hear. Their shows aren't half bad, however I like them significantly less than the vintage ones.
One can listen to radio shows at: Radio Spirits I think my admiration for voice acting stems from appreciation of vintage radio. (I hope to at some point to add a link discussing my favorite voice actors.)
