KJMZ is owned by Mollman Media, Inc. Studios are located on Flower Mound Road in eastern Lawton, and the transmitter is just west of the city.
Prior to the change in 1996 KJMZ was KRLG G-98 Adult Contemporary/Top 40 in the mid-1970s and rebranded as 98 FM KRLG featuring Album Orientated Rock from the late 1970s into the early 1980s then rebranded as the New 98 featuring the Adult contemporary format in the late 1980s and early 1990s.
The move was part of a series of FM reallotments across North Texas and Oklahoma to allow KBOC 98.3 Bridgeport to upgrade to cover Dallas/Fort Worth.
[2] On March 5, 2010, KJMZ was taken off the air temporarily after the station's studios were burglarized in the early morning hours.
For many years the call letters of KJMZ were housed at Dallas-Fort Worth's 100.3 which was also an Churban station now known as "KJKK" Jack FM.
