On October 12 , 1998 , KXPK changed to a younger-skewing alternative rock format , and added the syndicated " Howard Stern Show " in morning drive time , while still retaining the " Peak " moniker . In April 1999 , the station gained some brief notoriety when Stern made controversial comments on the Columbine High School massacre , with hundreds of complaints filed to the station . Possibly due to the controversy , KXPK moved to an All-80 's Hits format on September 5th of that year , again with the " Peak " moniker . In 2000 , the station was bought by Emmis Communications of Indianapolis , along with rhythmic contemporary station KKFR in Phoenix . The price tag for both stations was $ 108 million
