Question: What major river runs through the city where station KNVA is located? Passage:These two stations were once dual affiliates of both The CW and MyNetworkTV since their 2006 debuts: KWKB in Iowa City, Iowa, owned by KM Communications, which carried both The CW (as a primary) and MyNetworkTV (as a secondary), but dropped MyNetwork in September 2011; KNVA in Austin, Texas, owned by LIN Television, was the other, until it dropped the network on October 20, 2009. However, in March 2014, WKTC in Columbia, South Carolina, a locally owned station, switched its main channel's primary affiliation from MyNetworkTV to The CW, retaining MyNetworkTV as a secondary affiliation, making it one of three stations in the country that currently carry both The CW and MyNetwork on the same feed (WKTC would be joined in September 2016 by FTS-owned WPWR-TV in Chicago, licensed to Gary, Indiana, and in July 2018 by WUAB in Cleveland, licensed to Lorain, Ohio, in carrying both netlets on their primary channel). In addition, WTVY in Dothan, Alabama, a CBS affiliate owned by Gray Television, now carries MyNetworkTV on a digital subchannel which was previously affiliated with UPN, and also added a third digital subchannel for The CW. WTOK-TV in Meridian, Mississippi, also owned by Gray, has added a secondary MyNetworkTV affiliation to its then-Fox-affiliated digital subchannel and added another digital subchannel for The CW, in addition to ABC on its main channel.
