In NYC, it was WNCN, an all-classical station that competed with WQXR.
In those days, you could listen to the Met Opera on Saturday afternoon via WQXR, hear a full opera recording that evening on WNCN, and hear a recorded opera on Sunday evening on WQXR. Both stations had a policy of playing only complete works. After WNCN died, WQXR started avoiding vocal music except for the Met broadcasts and began to play individual movements from symphonies. End of a Golden Age of NYC radio.
