History
The station first signed on in August 1947 as KCSJ and has kept the same call sign over its long history. It was owned by the local daily newspaper, the Chieftain-Star Journal (now The Pueblo Chieftain). The station still carries the call letters which refer to the newspaper. Later it was bought by American Media and today is owned by iHeartMedia. Through the 1960s and 1970s, it played middle of the road music as well as news, farming and information shows. In the 1980s and 1990s, it moved to adult contemporary music coupled with talk shows and news, transitioning to all talk and news by 2000.
