KXNW, channel 34, is the MyNetworkTV-affiliated television station (with a former secondary affiliation with Antenna TV) for the Fort Smith/ Fayetteville, Arkansas market that is licensed to Eureka Springs, Arkansas. While Eureka Springs also is located in the Springfield, Missouri market, A.C. Nielsen considers this station to be part of the Fort Smith/Fayetteville market.
The station is owned by the Tribune Broadcasting subsidiary of the Tribune Media Company, as part of a duopoly with the CBS-affiliate KFSM-TV (channel 5); it is operated out of KFSM's facility on North 13th Street in downtown Fort Smith.
As of spring 2016, the over-the-air digital signal for the KXNW-DT1 simulcast on KFSM-DT2 was upgraded the into 720p high definition; thus offering a high definition feed for MyNetworkTV for the first time in the Fort Smith/ Eureka Springs, Arkansas area (and the entire Arkansas River Valley and Northwest Arkansas area and Beyond), with the Antenna TV programming being segregated out into its very own devoted Sub-Channel (via KFSM-DT3 Channel 5.3); although, the originating KXNW-DT1 feed remains in 480i 4:3 standard-definition. Antenna programming moved over to KFSM-TV's third subchannel, with Tribune Broadcasting replacing the hours programmed by Antenna TV with traditional syndicated programming, resembling most of Tribune Broadcasting's other MyNetworkTV affiliates.
