The frequency debuted in 1948 with the KRLD-FMcall sign. The station initially simulcast with Dallas stationKRLD. A number of different owners have owned the station, beginning with Times Herald Printing Company then KRLD, Inc. owned by family of former Dallas Mayor J. Erik Jonsson. The station was one of only three 24-hour FM stations in the Dallas market in the 1960s. A progressive rock format was instituted in the early 1970s.
The call letters changed to KAFM in 1972, and the station underwent a number of format changes through the 1970s and 1980s, including Top 40 as "Your Power Station Z92.5". Its current call sign KZPS originated from that format. At that time, the station was part of the J. Erik Jonsson family before it was sold to Bonneville Internationalin the summer of 1978.
92.5 was flipped to classic hits in 1987 and jazz before settling on a long-standing classic rock format, bringing John Boy and Billyon board in 1995, with the station imaging being "Ninety Two Five KZPS, the classic rock station". John Boy and Billy were later replaced by local hosts Sam "Bo" Roberts and "Long" Jim White in the mornings. Clear Channel bought the station from Evergreen Media, which had acquired it from Bonneville International in 1997. Notable disk jockeys of the many who have worked at the station include: Sam "Bo" Roberts and "Long" Jim White, Jay Philpot, Jon Dillon, Stubie Doak, Pamela Steele, Ed Budanauro, Benn McGregor, Jerry Vigil, Pete Thomson, John Shomby, and Paul Donovan.
