KISU FM 91.1 radio signed on the air for the first time with a tiny broadcast power of just 450 watts, barely making a ripple in the east Idaho radio world. Today with transmitters in both Pocatello, Idaho Falls and Rexburg, KISU broadcasts to a potential audience of almost 200,000 residents and an ever-growing number of public radio fans. KISU consistently has more listeners than many commercial stations in the market. KISU has made a name for itself with local and regional news as well as NPR, PRI and BBC content. KISU is also well-known for promoting local cultural and public affairs events through partnerships with Idaho State University, the Idaho State Civic Symphony, the Idaho Falls Arts Council, the City Club of Idaho Falls and other similar organizations.
