History

KWSU signed on the air on September 24, 1962, as KWSC-TV (standing for Washington State College, the name of Washington State University until 1959), and changed its callsign to KWSU-TV in 1969, a year before the launch of PBS. The station used the Washington State University cougar logo as its official logo until 1976. KWSU signed on KTNW on channel 31 on October 18, 1987. The channel 31 allotment in the Tri-Cities was briefly used in the late 1950s by KTRX, based in Kennewick, Washington, and since that station signed off, channel 31 in the Tri-Cities has been vacant until KTNW signed on.
