History

The station first signed on the air on July 3, 1997, as KGLB-TV; it originally carried programming from Paxson Communications' infomercial service, the Infomall Television Network (inTV). The station became a charter owned-and-operated station of Pax TV (now Ion Television) when the network launched on August 31, 1998; on that date, the station changed its call letters to KTPX-TV (the KTPX calls were previously used by NBC affiliate KWES-TV in Midland, Texas from 1981 to 1993).

Analog-to-digital conversion

KTPX-TV shut down its analog signal, over UHF channel 44, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 28.[3] Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 44.
