[4] On April 24, 1967, KSPS-TV first signed on the air,[5] from the basement of Adams Elementary of Spokane Public Schools.

It was affiliated with National Educational Television (NET), and moved to its successor network, PBS, on October 5, 1970.

A day later, the Friends of KSPS board also voted unanimously to move forward with taking full control of the station.

It was the first station to carry Mary Ann Wilson's Sit and Be Fit program, as KSPS serves as the primary production studio and distributor of the series since it debuted in 1987.

[8] On November 29, 2006, ice and wind caused the top 200 feet (61 meters) of the station's antenna at the Krell Hill transmission site to collapse, disrupting its off-air signal.

[9][10] The station's signal is multiplexed: KSPS-TV discontinued regular programming on its analog signal, over VHF channel 7, on February 17, 2009, the original target date on which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009).
