The station first signed on the air on December 21, 1996, as KINZ-TV (in reference to its original affiliation with the Infomall TV Network (InTV), the predecessor-of-sorts of Ion Television), carrying
infomercials for much of its schedule and programming from
religious broadcaster The Worship Network during the overnight hours. The station was to have originally given the call letters KAQV in its
construction permit to operate the station, which were changed prior to its sign-on. In early 1998, Paxson Communications (the forerunner to Ion Media) bought the station, and changed its call letters to KPXD-TV on January 13; the station became a charter owned-and-operated station of Paxson's new family-oriented broadcast network Pax TV (now Ion Television) when the network launched on August 31, 1998. As part of a wide-ranging deal that gave
NBC partial ownership of Pax, the former network's owned-and-operated stations as well as many of its affiliates provided sales and marketing assistance for Pax TV stations in several markets, with KPXD entering into a
joint sales agreement with
KXAS-TV (channel 5; which NBC had owned 76% interest in at the time, it is now owned by the network outright). In 2003, Pax TV decided to scale back its programming due to financial losses, resulting in much of the afternoon time slots on its stations' schedules being filled with infomercials. After Pax was rebranded as i: Independent Television on June 30, 2005, Worship Network programming moved to one of KPXD's
digital subchannels (originally its third subchannel, then to its fourth subchannel after Ion Life (later
Ion Plus) and
Qubo launched, before Worship was dropped on January 31, 2010). In September 2020, Ion Media was sold to the E. W. Scripps Company, marking the latter company's first entry into the Dallas–Fort Worth market. On February 27, 2021, shortly after the sale closed, Ion Plus and Qubo ceased broadcasting, and KPXD-DT2 and DT3 switched to
Court TV and
Grit, sharing the affiliations with
KDAF (channel 33) and
KSTR-DT (channel 49) respectively. The next day, KPXD-DT4 switched from Ion Shop to
Laff, sharing the affiliation with
KUVN-DT (channel 23). On June 28, 2021, Court TV was removed from KPXD-DT2, and replaced with
Bounce TV, sharing the affiliation with KUVN-DT. On that same day, QVC and HSN were removed from KPXD-DT5 and KPXD-DT6 respectively, and began showing previews of Scripps-owned
Reality TV networks Defy TV and TrueReal respectively. Both networks launched on July 1, 2021. On October 1, 2021,
Newsy was added to channel KPXD-DT7. ==Newscasts==
