KGNC entered the Amarillo, Texas, community in 1935 when the Amarillo Globe-News Publishing Co., headed by Gene Howe, organized Plains Radio Broadcasting Co. The company purchased WDAG and KRGS, which by then were well-established stations, and merged the two into KGNC. Ted Taylor was general manager, and Wes Izzard moved over from the newspaper to become production manager.
The call letters represented the Globe-News Co., preceded by the K as dictated by the Federal Communications Commission. KGNC joined the NBC National News Network on Jan. 1, 1937. The first coast-to-coast program aired in Amarillo was the National Farm and Home Hour. KGNC also made Amarillo's first FM broadcast Christmas Eve in 1958.
KGNC-AM 710 covers a 109-county, five-state area with 10,000 watts.
