release announcement by the network, KPXJ was confirmed as The CW's Shreveport charter affiliate. Since the network chose its charter stations based on which of them among The WB and UPN's respective affiliate bodies was the highest-rated in each market, KPXJ was chosen to join The CW over KSHV-TV as it had been the higher-rated of the two stations at the time of its agreement despite channel 45 having had a four-year headstart on KPXJ operation-wise. Eight days later on March 15, News Corporation announced that it had signed an agreement with White Knight Broadcasting, in which KSHV would become the market's MyNetworkTV affiliate, as part of a deal that also saw Fox-affiliated sister station WNTZ-TV in Alexandria being committed to join the network under a secondary affiliation. (That agreement was separate from an agreement that Communications Corporation of America signed for KLAF-LD [now an NBC affiliate] in Lafayette, KWKT-TV in Waco, Texas and WEVV-DT2 in Evansville, Indiana.) KSHV officially joined MyNetworkTV upon that network's launch on September 5, 2006; although, unlike other WB- and UPN-affiliated stations that were committed to join MyNetworkTV, The WB's prime time programming was carried by KPXJ 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 September 17, the day before the network formally ceased operations. KPXJ remained a UPN affiliate until September 15, and officially affiliated with The CW when that network debuted on September 18. The station also carried classic television series from the Retro Television Network from September 2008 to January 2009. KSHV-TV discontinued regular programming on its analog signal, over UHF channel 45, on February 17, 2009, the original date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate. On April 24, 2013, Irving, Texas–based Nexstar Broadcasting Group announced that it would acquire the 19 television stations owned by Communications Corporation of America and White Knight Broadcasting for $270 million in cash and stock. Because Nexstar could not legally purchase KMSS under FCC ownership rules as Shreveport has only eight full-power stations (the FCC requires a market to have at least eight unique owners once a duopoly is formed), and KTAL and KMSS were among the four highest-rated stations in the Shreveport market at the time of the transaction, plans called for KMSS to be acquired by Westlake, Ohio-based Nexstar partner company Mission
