KRDK-TV, channel 4, is a television station serving Fargo, North Dakota and Grand Forks, North Dakota, which is affiliated with multiple networks on various digital subchannels. It is licensed in Valley City, North Dakota, its transmitter is located near Galesburg, and its studios are in Fargo. The station launched in December 1954 as KXJB-TV, the CBS affiliate for the market.
KXJB consolidated with NBC affiliate KVLY-TV in 2003 under a local marketing agreement. In 2014, the station's non-license assets were acquired by KVLY's new owner Gray Television: due to increasing FCC scrutiny surrounding local marketing agreements and similar arrangements, Gray decided against having the station acquired by an affiliated third-party to maintain the LMA. Its CBS programming was moved to KVLY's second digital subchannel in December 2014, and KXJB's license was sold to the minority-owned Major Market Broadcasting, who re-christened the station KRDK-TV. The station returned to the air during January 2015 carrying several digital television networks.
The high KXJB-TV mast, located near Galesburg, North Dakota, was the second tallest man-made structure on Earth when it was built in 1966.
