The one MAJOR question which I have NEVER seen an answer thereto is this...
WHEN/WHERE/WHO expanded "record dealers" from their original format...where they were franchised as "dealers" for single makes of records ("Buy this new release at your Victor(usw.) dealer NOW!") to "record stores"as I recall them from the fifties...which offered virtually ALL record labels!
I have a few c.194? advertising lists from record stores, that seem to offer ALL the labels...so the change must have taken place sometime in the thirties...?!
