In the 1980s KISC competed with top 40 KZZU. However as hard rock and rap began to dominate Top 40 Radio, KISC shifted to Adult top 40 and eventually A very "hot" leaning AC format. In the 90s KISC would take pot shots at KXLY for playing too much "soft sleepy music". When KXLY flipped to Adult Alternative and then to Country, KISC became Spokane's only Adult Contemporary station. KISC has been Spokane's home of Casey Kasem. The station aired his weekley Adult Contemporary countdowns Sunday Mornings and now airs his 80's countdowns in about the same slot as they aired his Adult Contemporary Countdowns from 1992 to 2009. KISC has aired a locally produced request and dedication show in the 1990's then switched to the John Tesh show. Most recently KISC has brought back Delilah's love songs show to Spokane that aired on competitor KXLY in the 1990's
