Here's a group I can support. SPERDVAC is the Society to Preserve and Encourage Radio Drama, Variety and Comedy. Their goal is to keep Old time radio alive and available for future generations. Personally I am in awe. Without groups like this half a century of radio history could be lost.
The club was started by a group of collectors of old radio shows back in 1974 to trade shows with each other. They then established libraries for members to borrow the shows. These libraries have expanded to over 20,000 shows , scripts and even some videos of conventions. Their membership was over 1,600 at its peak. Sadly the membership today has dwindled to a little more than 1,000.
Every month, members of this old time radio group meet at local housings to discuss radio shows and their years, many of which a guest speaker, whom was associated with radio programs at the time it was on the air, attends. Their monthly publication "The Radiogram" a monthly newsletter focused on old time radio and the related hobbies.
They have 8 meetings and a convention every year. But as the stars of the golden age of radio age, the line ups are more and more difficult to put together. Their focus on building a library of radio drama continues unabated. They convert the old 16" transcription discs to digital formats continually. The effort is building the most important library in all of radio land. Their podcast is here.
