KNDU (channel 25) in Richland operates as a semi-satellite of KNDO, serving the Tri-Cities area; this station maintains its own studios on West Kennewick Avenue in Kennewick. As a KNDO semi-satellite, it simulcasts all network and syndicated programming as provided through its parent, and the two stations share a website. However, KNDU airs separate commercial inserts and legal identifications. Local newscasts, produced by KNDU, are simulcast on both stations. KNDO serves the western half of the Yakima/Tri-Cities market while KNDU serves the eastern portion. The two stations are counted as a single unit for ratings purposes. Master control and some internal operations are based at the studios of sister station, fellow NBC affiliate and company flagship KHQ-TV on West Sprague Avenue in downtown Spokane.
