KPLC-TV began broadcasting in the summer of 1954. Owner T.B. Lanford of Shreveport had previously signed on KPLC AM radio and was eager to expand into television.
The station was later purchased by a St. Louis group headed by investor Elliot Stien. He visited KPLC frequently along with his friend, St. Louis Cardinal baseball legend Stan Musial.
In 1970, G. Russel Chambers purchased KPLC-TV from the St. Louis group and dramatically increased the station' s coverage by adding a 1,500 foot tower, providing a quality signal for the NBC affiliate as far north as Leesville, as far east as Lafayette and to the Gulf of Mexico. FCC regulations required that the radio stations be sold. Perry Sanders purchased the AM/FM combo and changed its call letters to KLCL.
In 1986, Cosmos Broadcasting, a subsidiary of Liberty Life Insurance Company, took over, bringing high-tech improvements, including stereo broadcast and other state of the art innovations. Today, KPLC prides itself as one of the top news stations in the country, consistently in the top five nationwide in news ratings and shares.
In 2000, Cosmos Broadcasting assumed the name The Liberty Corporation. KPLC was sold to Raycom Media in 2006.
