KRMG was founded by Kerr-McGee oil company partners Robert S. Kerr and Dean McGee. Kerr, at the time a US Senator, wanted a station that would cover both Tulsa and Oklahoma City. KRMG had to protect co-channel stations to the north and south, thus, six towers and 50,000 Watts were employed to achieve the desired coverage pattern.
KRMG was a Middle-of-the-road music station from the 1950s through the 1970s, when it adopted a full-service adult contemporary format. In the 1990s, the station dropped music altogether and made the transition to the current news talk format. The station also carries Fox News.
KRMG is credited with the development of Tulsa's River Parks. The station first hosted the Great Raft Race in 1973. It was a floating race down the Arkansas River from Sand Springs to Tulsa. It was the first major event to attract people to the Arkansas River. The River Parks authority was formed in 1974 to develop the area.
Former KRMG hosts include John Erling, Ann Williams, Dianna Proffitt, Dick Andert, Jerry Vaughn, Watson Jelks, Johnny Martin, Trey Callaway, and Wes Minter.
