carrying the final two weeks of that network's programming between 12:00 a.m. and 2:00 a.m. weeknights and 11:00 p.m. and 2:00 a.m. Sunday/early Mondays until The WB ceased operations on September 17. KPXJ officially affiliated with The CW the following day on September 18, 2006, at which time the station changed its on-air branding to "KPXJ CW 21". On December 30, 2008, Wray Properties Trust (through KTBS, LLC) filed an application with the FCC to purchase KPXJ from Minden Television for $10.3 million, which would create the market's first (and only) legal television duopoly. As the Shreveport–Texarkana market has only eight full-power television stations, the minimum allowed to create a duopoly under FCC rules, it is the only duopoly legally allowed in the market. KTBS, LLC included in its license transfer request a "failing station waiver," indicating that KPXJ was in an economically non-viable position—noting that the station had lost revenue for the previous three years, and had averaged only a 1 audience share point for all but two sweeps ratings books while never reaching over a 4% share—and that FCC should relax ownership limits that apply to the Shreveport–Texarkana market so that Channel 21 could stay on the air; that limit (found in CFR§73.3555(b)(2) of the FCC's rules) permits ownership duopolies in markets with at least eight full-power stations, whereas Shreveport–Texarkana has only seven. The transfer was completed on August 3 of that year, officially making KTBS-TV and KPXJ directly owned sister stations. Subchannel history KPXJ-DT2 KPXJ-DT2 is the MeTV-affiliated second digital subchannel of KPXJ. Over the air, it broadcasts in standard definition on channel 21.2.

KPXJ launched a second digital subchannel on virtual channel 21.2 in September 2005, which originally served as a standard definition simulcast of the station's primary channel. On June 20, 2011, KPXJ-DT2 converted into an affiliate of MeTV, through an agreement between its owner, Weigel Broadcasting, and KTBS, LLC.
