In March 1961, NBC reached an agreement with KTAL-TV to become the network's primary affiliate for the enlarged Shreveport-Texarkana market, replacing KTBS-TV (channel 3), which had served as Shreveport's original NBC affiliate since the station launched on September 3, 1955; KTBS's contract with NBC was not scheduled to expire until September 1962, though there had been speculation that KTBS and KTAL would swap primary affiliations before its expiration. On September 3, KTAL took over as the exclusive NBC affiliate for the Shreveport–Texarkana market; KTBS-TV concurrently became the market's exclusive ABC affiliate. Coinciding with the affiliation switch, KTAL-TV moved its primary operations into a new studio facility on Market Street in northeastern Shreveport, retaining its original Summerhill Road studios to primarily serve as a Texarkana news bureau. (FCC regulations had been changed in 1952 to allow for a broadcast station to house their main studio within of their city of license.) The FCC subsequently granted a reassignment of the KTAL license and its accompanying VHF channel 6 allocation to Shreveport on October 11, 1961.
