KOBM signed on in 1942 as KBON. It changed to KLNG on July 1, 1970. By early 1977, KLNG identified as "Newsradio 149". However, on June 1 of that year, KLNG became KYNN and took on a country music format. On April 9, 1985, at 6 a.m., the station flipped to oldies as KEDS. Due to poor ratings, on July 2, 1987, KEDS dropped the oldies format and began simulcasting KEZO-FM. The simulcast would last until the early 1990s, when KEZO flipped to sports talk, and would adopt the KOSRcall letters in March 1996. The sports format would last until April 25, 2005, when then-sister station KOMJ swapped formats, with 1490 adopting KOMJ's adult standards format and call letters. On August 1, 2013, a Federal Communications Commission agent attempted to inspect the studios of KOMJ. The address listed on filings with the FCC, 10714 Mockingbird Drive, was in fact the address for the Journal Broadcast Group studios. KOMJ owner, Cochise Radio Partners, did not have staff or equipment at that location. Journal Broadcast Group had sold the station to Cochise Radio Partners in 2007. Less than a year later, in March 2014, the FCC fined Cochise Broadcasting, LLC $17,000 for "failing to operate and staff a main studio with a public inspection file". On October 17, 2014, Cochise Radio Partners announced they were selling KOMJ to Walnut Radio, LLC for $450,000. The sale between Cochise and Walnut closed on January 2, 2015. Five days later, the station dropped the middle of the road music from its format for adult standards, classic hits, and oldies. At exactly 6:00 p.m. on January 7, "Boomer 1490" was officially launched with a live listening party at Gorat's Steakhouse in Omaha. The first song played under the new Boomer format was "Good Vibrations" by The Beach Boys. In June of that year, long time radio legend Dave Wingert became the new Morning Show host. In May 2016, an FM translator was added on 104.1 FM, giving the station an AM/FM combo. The station is now known as "Boomer Radio." The call letters were changed to KOBM on December 11, 2018. On April 1, 2019, the station changed call letters to KIBM, with the KOBM call letters moving to 1420 AM.
Translator
In addition to the main station, KIBM is relayed by two FM translators in the core Omaha metro and suburbs.
