WJET-TV signed on as the third station in Erie during the 6 p.m. hour on April 2, 1966. Owned by Jet Broadcasting along with WJET radio, it aired an analog signal on UHF channel 24 and the first program shown was a 24-hour movie marathon. The station immediately joined ABC. Previously, ABC had been limited to off-hours clearances on NBC station WICU-TV (channel 12) and CBS outlet WSEE-TV (channel 35) until this point. In January 1998, Nexstar acquired WJET-TV. Later that year, it began performing non-programming functions for Mission Broadcasting-owned WFXP as was standard for most Nexstar stations. That station was then consolidated into WJET's facilities.
