The station was assigned the call letters KFMQ-FM beginning in 1958. On 1992-10-30, the station changed its call sign to KYNN, then on 1995-04-01 to KGDE, then on 1995-04-03 to KYNN, and on 1997-04-17 to KGDE. On 1998-04-24 the call letters changed again to KZFX, then on 2002-02-01 to KLTQ, and finally on 2007-12-28 to the current KOOO. KOOO was previously assigned to a Dallas, Texas station (which was also known as KEWS-FM for a time). Before that, KOOO was a country music station in Omaha, simulcasting on 1420 AM and 104.5 FM.
On August 11th, 2014, 101.9's website has changed to whatever1019.com, and the logo was replaced by a picture of a genie's lamp, with the words, "WHAT'S YOUR WISH?". At the same time, KOOO removed all imaging on the former Big O. The new format, according to website registration, was to be country as 101.9 The Hog. These rumors were confirmed, as 101.9 began running liners the following day saying that the following day at 4PM, "your wish will come true". 1019thehog.com also ran a countdown clock to the same time, saying the similar "You Wish Comes True  days  hours  minutes  seconds August 13, 2014". However, in a similar way as WRNW in Milwaukee did it in 2004, KOOO instead flipped to 80s-based Classic Rock as 101.9 The Keg at the promised time. The last song on 101.9 The Big O was Goodbye by Night Ranger.
