KGYM signed on as KCRG on December 20, 1947, under the ownership of the Cedar Rapids Gazette Company (later known as Gazette Communications). The Gazette Company had launched Cedar Rapids' first FM station, KCRK-FM 96.1, a month earlier and had applied for a construction permit for a television station on channel 9 that year. (KCRK-FM signed off in 1954 as FM radio was still in its infancy and the station proved to be unprofitable.) In 1953 the Gazette Company consolidated its interests with the Cedar Rapids Television Company, another group interested in the channel 9 license, and in October 1953 the call letters of the radio and television stations were changed to KCRI. After the Gazette Company bought out the Cedar Rapids Television Company's stock on August 27, 1954, the KCRG call letters were restored to both the AM and TV stations.
During the early 1990s KCRG was a country music station, and it later adopted a news/talk format. By 2000 the station had moved to its current sports talk format but continued to simulcast KCRG-TV's newscasts and ABC's World News Tonight for radio listeners. KCRG radio adopted the nickname "The Zone" in 2003.
On July 10, 2006, Gazette Communications announced that KCRG was being sold to owners of another local broadcaster, KZIA FM 102.9, subject to FCC approval. The sale was finalized on October 31, 2006, and the call letters were changed to KGYM as a result of the sale. After the acquisition, KGYM ended its simulcasting of KCRG-TV's newscasts, and KGYM's studios moved from downtown Cedar Rapids to KZIA's studios on the city's southwest side.
KGYM currently broadcasts ESPN Radio programming along with Iowa State University sports, college basketball and the NFL from Westwood One, the IndyCar Series, Minnesota Twins baseball on 107.5 FM and area high school football and basketball games. It also carried Cedar Rapids Kernels games before sharing rights with KMRY, another Cedar Rapids radio station, during the 2006 season. Kernels games moved exclusively to KMRY starting in 2007.
Local talk shows include The Gym Class hosted by KGYM sports director Scott Unash and former Cedar Rapids Gazette sports editor Mark Dukes and The Todd Brommelkamp Show with Alex Kuhn hosted by Voice of the Hawkeyes magazine editor Todd Brommelkamp and St. Louis native Alex Kuhn.
