SPERDVAC (The Society to Preserve and Encourage Radio Drama, Variety and Comedy) is a non-profit organization dedicated to preserving the history and the recordings of old-time radio, with the following goals:
To provide the finest collection of quality radio programs that members may listen to and duplicate for their own collections. To seek out and honor the people who made radio's “Golden Age” possible. To promote and encourage drama, variety and comedy programs—old and new—on radio today. To collect and maintain for members and other interested people, a library of radio history and to use this material in the publication of a “newsletter” or special brochures in preparation of an accurate and complete account of radio history from its earliest days to the present. To contribute to the support of non-commercial radio stations interested in and aiding the goals of the society, including broadcasting “old-time” radio programs. To alert members to trends in drama, variety and comedy broadcasting; and to publish special radio program listings and news releases to inform members and the general public.
The website also offers a selection of old time radio show episodes to listen to for free.
