Prior to 2006, what was then called KWBZ operated solely as a local cable TV station and was owned and operated by KCBD-TV, the local NBC affiliate. At that time, channel 22 was occupied by KUPT, an affiliate of UPN. On January 1, 2006, after the station was acquired by Ramar Communications, KUPT moved to channel 14 in Lubbock (now MyNetworkTV affiliate KMYL-LD), and the WB affiliation moved to channel 22.
KWBZ-TV became a full power broadcast affiliate of The WB (via The WB 100+ Station Group as on cable) on January 1, 2006. Twenty-four days later, Warner Bros. Television, which owned The WB, and CBS Corporation, owner of UPN (channel 22's former network as KUPT), announced a merger of those two networks to take effect on September 18, 2006; the new network operating under the name of "The CW". KWBZ signed on to become a CW affiliate, resulting in new call letters (KLCW-TV was adopted on June 30, 2006) and a rebranding (Lubbock CW). The station's feed is still affiliated with The CW Plus with local inserts and advertising placed by KJTV-TV and Ramar.
On October 19, 2020, Ramar announced that it would sell KLCW (and its accompanied low-power stations) to Gray Television (owner of KCBD) for $10 million.[2] Concurrently, SagamoreHill Broadcasting would acquire sister station KJTV for $5 million.[3] Gray would provide services to KJTV through a shared services agreement.[4] The sale was completed on December 31.[5]
Because it was granted an original construction permit after the FCC finalized the DTV allotment plan on April 21, 1997,[7] the station did not receive a companion channel for a digital television station. Instead, on or before February 17, 2009, the original date of the digital TV conversion for full-power stations, KLCW-TV would be required to turn off its analog signal and turn on its digital signal (called a "flash-cut"). As of September 2008, the station's digital signal began broadcasting on its pre-transition UHF channel 43, using virtual channel 22.
