the second television station in the market to launch stereo broadcasting, doing so in May 1987. In January 1999, KTBS, LLC assumed partial operational responsibilities for Pax TV owned-and-operated station KPXJ (channel 21) under a joint sales agreement (JSA) with its owner at the time, Paxson Communications (now Ion Media Networks). Under the terms of the agreement, which was modeled similarly to other outsourcing agreements between Paxson and an owner of a local major network affiliate during that timeframe, KTBS also rebroadcast its 5:00 and 10:00 p.m. newscasts on channel 21. On June 17, 2003, Paxson announced it would sell KPXJ to KTBS, LLC for $10 million; the FCC rejected the application as agency ownership rules prohibited common ownership of two television stations in a single market if there are fewer than eight independent full-power station owners. As such, Paxson reached an agreement to sell the KPXJ license to Minden Television Company LLC (owned by Lauren Wray Ostendorff, daughter of Edwin N. Wray Jr., part-owner of KTBS), an indirect subsidiary of Wray Properties Trust, for $10 million. After the purchase was finalized, the Wrays converted KPXJ into the market's UPN affiliate. On December 30, 2008, KTBS, LLC (by way of Wray Properties Trust) filed an application with the FCC to purchase KPXJ from Minden Television for $10.3 million, which would create the market's first legal television duopoly. As the Shreveport–Texarkana market has only eight full-power television stations (the minimum required to create a duopoly under FCC rules), it is the first 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.
