During the 1950s, WQXR-FM's programming was also heard on the Rural Radio Network on several stations in Upstate New York, including ones targeting Buffalo, Rochester, Syracuse and Albany. This ended when the RRN stations were sold to Pat Robertson's Christian Broadcasting Network. Both the AM and FM sides continued to simulcast each other until 1965, when the FCC began requiring commonly owned AM and FM stations in large markets to broadcast separate programming for at least part of the day. WQXR-FM concentrated on longer classical works, while WQXR (AM) aired lighter classical music and talk programs produced in conjunction with "The New York Times". While this plan gave classical music fans two options, it also increased expenses for the stations.
