About KOLRThe station went on the air as KTTS-TV on March 14, 1953, and was formed by the Independent Broadcasting Company, which also owned KTTS radio (1400 AM, now KSGF on AM 1260, and 94.7 FM). Channel 10 began operations in downtown Springfield, at the southwest corner of Walnut and Jefferson Streets, in the Springfield Chamber of Commerce building. Since its inception, the station has been a CBS affiliate; however, it also had a secondary affiliation with ABC, which it shared with major NBC affiliate KYTV (channel 3) until KMTC (channel 27, now KOZL-TV) debuted on in 1968.
In 1971, the station's call signs were changed to KOLR. The station's transmission tower, at 2,000 feet (610 meters), is the second tallest in the United States, only 19.2 meters (63 feet) lower than the highest. In 1972, the radio stations were sold to Great Empire Broadcasting of Wichita, Kansas.
