Back around 1934-35 there was an outfit called the American Broadcasting System-not to be confused with what in '34-35 was still part of David Sarnoff's RCA-NBC empire as the Blue Network. Pittsburgh's KQV [which, ironically would affiliate with Blue from 1941-45 and would later be owned by ABC from '57-74] was a member of ABS. Does anybody know the history of the network?
