Old Time Radio Concept

Spectral Shadows is a long serialized story that takes place in various times, on various planets, and in various dimensions. However, the author finds that it is expedient to write any segment of the story that is currently visualized while it is fresh, rather than putting things on hold in order to write the saga in a linier fashion. This results in the availability of a lot of odd episodes from various otherwise unwritten serials. 
The author finds this to be similar to the situation that exists in the Old Time Radio fandom where much material has been lost, but is sometimes recovered in odd episodes which lack their surrounding context. This is also a situation familiar to the Doctor Who fandom where only one episode of a serial may currently be available, but fans still want to see it.
Thus, the author fancies that the episodes available online are modern novelizations of all the currently available episodes of an Old Time Radio serial called Spectral Shadows that would have aired from 1939 to 1955, having had thousands of episodes, the majority of which were not professionally preserved, but which may still be around in private collections and such. And any new episodes that appear are regarded as recent discoveries.
The author admits that the Old Time Radio concept is unnecessary to the enjoyment of the series and may be freely disregarded, unless one is an actual Old Time Radio fan who finds the concept relatable. In which case interested individuals should read the author's blog post on the subject.
