About KPLC 7KPLC-TV signed on September 29, 1954. Owner T.B. Lanford of Shreveport had previously signed on KPLC radio (1470 AM, now KLCL, and 99.5 FM, now KNGT) and was eager to expand into television, giving the new station the same callsign as their radio sisters.
The station was a major beneficiary of a quirk in the Federal Communications Commission (FCC)'s plan for allocating stations. In the early days of broadcast television, there were twelve VHF channels available and 69 UHF channels (later reduced to 55 in 1983). The VHF bands were more desirable because they carried longer distances. Since there were only twelve VHF channels available, there were limitations as to how closely the stations could be spaced.
