KXOK Radio St. Louis

KXOK St. Louis went on the air on September 19, 1938 at 1250 on the AM dial. It moved to 630 two years later. One of the members of the air staff was Paul Aurandt, who would later become newscaster Paul Harvey. In its early days, KXOK was affiliated with the Mutual Broadcasting System and later NBC.?? In 1960 it was sold to the Storz brothers who changed the format to all music focused on the top 40 hits of the day. KXOK soon became the pre-eminent rock & roll station in St. Louis, driving its main competitor, WIL, to switch to country music in 1967.
