[ARSCLIST] vinyl 78's

[Tom Fine <tflists@xxxxxxxxxxxxxxxxxxx>]

What's the history of vinyl 78's? I have a small pile from I think the very early 50's, these are 
pop and country tunes. Was vinyl used for 78's in any mass quantities previous to when vinyl LPs 
were mass-manufactured? The "newest" vinyl 78's I know of are kiddie records pressed in the 
mid-60's. Aside from novelty stuff, was the medium used after the mid-60's?

Thanks for the coming history lesson!
