Stations are arranged in alphabetical order by state and city of license. Note: This list does not include WJZ (now WABC (AM)) in New York or WENR (which later merged into WLS (AM)) in Chicago, which were NBC-owned Blue Network stations prior to the split of the two networks in 1942. Two other stations, WMAL (now WSBN) in Washington, D.C. and KGO in San Francisco, are omitted; these Blue Network affiliates were managed by NBC but owned by other entities. In addition, KOA in Denver was managed by NBC from 1930 until 1941, when it was purchased by NBC.
