KSIS broadcasts a blend of news, talk, and sports radio programming. The station derives some of its news programming from ABC News Radio. Notable syndicated talk programming on KSIS includes weekday shows hosted by Rush Limbaugh, Sean Hannity, and Michael Medved. KSIS airs St. Louis Cardinals baseball games as a member of the St. Louis Cardinals Radio Network.
Local real estate agent Angel Morales hosts a Saturday morning Spanish language talk program called "Sábados Latinos". The name translates to "Latino Saturdays" in English. The show is part of the station's outreach to mid-Missouri's growing Latino population.
KSIS first signed on at 1050 kHz as a 1,000 watt daytime-only station on February 18, 1954. The station was licensed to Yates Broadcasting Company, Inc., with Carl W. Yates, Jr., serving as president and general manager.
