KNDU, virtual channel 25, is an NBC affiliate television station serving south-central and southeastern Washington state. The station, which broadcasts on digital channel 26, is based in the Tri-Cities region of Pasco, Richland and Kennewick. The station is licensed to Richland, but its studio is located in Kennewick. It is a sister station to KNDO in Yakima and KHQ in Spokane. Both stations are owned by Cowles Publishing Company of Spokane as part of The KHQ Television Group.
Though identifying as a station in its own right, KNDU is considered a semi-satellite of KNDO. It clears nearly all of KNDO's syndicated programming, though it airs separate identifications and a separate newscast. On satellite, KNDU is only available on Dish Network, while DirecTV carries KNDO instead.
