KDLT, is the NBC affiliated television station in Sioux Falls, South Dakota, serving Eastern South Dakota, Southwestern Minnesota, Northwestern Iowa and parts of Nebraska. KDLT started broadcasting from Mitchell, South Dakota as KORN-TV on channel 5, an ABC affiliate. The station’s original call letters were intended to honor the famous Mitchell Corn Palace. In 1972, the station changed its call letters to KXON-TV. Prior to 1982 KXON changed its call letters to KDLT when it was purchased by Dakotaland Broadcasting. Dakotaland Broadcasting eventually sold KDLT to Heritage Broadcasting in the mid 80’s. In 1982, KDLT and another station in the market switched affiliations, therefore making KDLT the NBC affiliate. Eventually KDLT moved its main studio to Sioux Falls in August of 1987. In 1994 Red River Broadcast Co., LLC purchased KDLT and moved the city of license to Sioux Falls on September 8, 1998 when they began broadcasting on channel 46 from a new 2000 foot tower in Rowena, SD.
