We could start with a definition of the Golden Age of Radio, but that in iteself seems a point of great controversy with Golden Age Radio fans and scholars alike. Most can agree that it falls somewhere between 1929 and 1957, but many would extend that well into the 1960's. Indeed, some the Radio Drama revivals continued well into the 1980's. Scholars and academics, aside, most fans 'know it when we hear it', irrespective of it's chronological date.
Our Spotlight on The Golden Age of Radio generally defines the Golden Age Radio Era as that period between the advent of commercial radio, 1921, and somewhere between 1965 and 1968.
For our purposes, we use 1921 - 1967.
As a point of reference we offer the following widely accepted definitions, for comparison:
1909 - 1962. Rationale: The invention of the Audion Tube by Dr Lee DeForest in 1909, and the end of both the "Yours, Truly, Johnny Dollar" and "Suspense" in 1962.
1921 - 1984. Rationale: The first commercial broadcast in 1921, through the last run of original CBS Radio Mystery Theatre (CBSRMT) broadcasts in 1984. Hyman Brown's excellent CBSRMT productions not only embodied all of the unique, high production value, well acted dramatic presentations of the very best examples of the Golden Age of Radio. Indeed, it was Hyman Brown's hope that CBS Radio Mystery Theatre would encourage others to realize the continued commercial viability of Radio dramatizations.
1920 - 1950. Rationale: Some people prefer to define the Era of Early Radio as separate from the remaining radio drama, variety, and comedy productions during the Cold War Years. They might further break the period down by defining 1950 - 1960 as 'The Silver Era', and Post-1960 radio drama as 'Revival'.
1924 - 1939. Norman Corwin is quoted as stating that The Golden Age of Radio effective ended with the adoption of The Television by the networks. From a purist standpoint, there's a poignant truth in Corwin's observation. Network Broadcasting has always been a ruthlessly commercial endeavor. There's no doubt that the advent of popularly available television sets marked the beginning of the end of network emphasis on Radio as the most viable commercial medium.
I began collecting Golden Age Radio in 1962, capturing both early FM rebroadcasts of Golden Age Radio shows, as well as recording the shows still airing over AM Radio at the time. I recorded them to tape. When I began collecting in earnest, it was the CBS Radio Mystery Theatre series that I attempted to find the most of, acquiring what I thought was a very extensive collection of over 600 at one time. . . . only to discover that my collection represented only a fraction of the CBSRMT shows produced. Needless to say, I'd 'caught the bug'.
