2015 season, KWTV diverted broadcasts of the team's Thursday night preseason games to sister station KSBI. (Prior to its acquisition of channel 52, the Thursday games forced KWTV to air first-run episodes of the CBS reality series Big Brother in late night to allow viewers to watch or record the affected episode on a delayed basis.) KWTV/KSBI's contract with the Rams concluded after the 2015 season as a result of the team's move to Los Angeles effective the following year. (Ironically, most Rams regular season games air on Fox affiliate KOKH-TV by way of Fox's contractual rights to the NFL's National Football Conference, while KWTV only carried regular season games featuring the team if CBS was scheduled to carry an interconference games against an opponent in the American Football Conference, or after 2014, an NFC-only matchup to which Fox passed the rights to CBS under NFL cross-flex broadcasting provisions.) On July 24, 2015, Griffin announced an agreement with the Oklahoma Secondary School Activities Association (OSSAA) that would return high school football coverage to KSBI after a five-year sabbatical; as a byproduct of the deal, KWTV also maintained partial over-the-air rights to the OSSAA Class 5A and 6A football championships, which were split between the station's main channel, its News 9 Now subchannel and KSBI. News operation , KWTV-DT broadcasts 41½ hours of locally produced newscasts each week (with seven hours on weekdays, four hours on Saturdays and two hours on Sundays) (with a half hour of local sports programming on Sundays). The News 9 Weather team also provides local weather updates and, in the event of significant severe weather situations (such as a tornado warning) affecting portions of the market, audio simulcasts of long-form severe weather coverage for the Griffin-owned Radio Oklahoma Network and, through a content agreement with locally based Tyler Media Group, the Oklahoma City radio cluster of KOKC, KOMA (92.5 FM), KMGL (104.1 FM), KJKE (93.3 FM) and KRXO-FM (107.7 FM). KWTV also features select stories filed by Tulsa sister station KOTV-DT during its newscasts, and partners with that station to cover news events within the Tulsa market; both stations co-produce the sports analysis program, Oklahoma Sports Blitz, which airs Sundays at 10:25 p.m. on both stations and has been hosted since its August 2001 debut by KWTV sports director Dean Blevins and KOTV sports director John Holcomb. KWTV has long had a rivalry with KFOR-TV, vying
