The two stations share studios on West 1700 South in Salt Lake City; KTVX's transmitter is located atop Farnsworth Peak in the Oquirrh Mountains.

KTVX has a large network of broadcast translators that extend its over-the-air coverage throughout Utah, as well as portions of Idaho, Nevada and Wyoming.

KTVX traces its history back to the November 1946 sign-on of W6XIS, the first television station in Utah, which operated under an experimental broadcast license.

Cindy Sheehan appeared in a paid political message protesting the Iraq War and the ad was submitted to the four major network stations in the market (KSL-TV, KSTU, KTVX and KUTV).

KTVX management declined the offer saying that "the content could very well be offensive to our community in Utah, which has contributed more than its fair share of fighting soldiers and suffered significant loss of life in this Iraq war.

"[8] On November 16, 2006, Clear Channel announced plans to sell all of its television stations, including KTVX,[9] after being bought by private equity firms.

[11] However, on August 22, KTVX was removed from the sale after Univision Communications, owner of KUTH (channel 32) and of which Providence Equity Partners holds a 19 percent stake, canceled its plans to purchase KUTF (channel 12) in Logan thus alleviating the need to sell KTVX (although sister station KUCW was eventually sold to High Plains Broadcasting due to FCC single-market ownership limits but continued to be managed by Newport Television).

[13] The JSA and SSA between KTVX and KUCW was terminated upon the completion of the sale, which occurred on December 3, as both stations officially became co-owned for the first time since Clear Channel sold the pair back in 2008.

On April 26, 2010, KTVX became the third television station in the Salt Lake City market to begin broadcasting its local newscasts in high definition; with the conversion came the introduction of a new HD-compatible news set and graphics package.

In addition, KUCW debuted a KTVX-produced local entertainment program called The Daily Dish on September 7, 2010 (which has since been moved to KTVX and was converted into an hour-long midday newscast at 11 a.m.).

[31] In 2021, the station was tricked into promoting a fake sexual wellness product, "invented" by a team working for late-night political commentary show Last Week Tonight, called the "Venus Veil", which was actually just a blanket; the show's team paid KTVX $1,750 to feature the fake product and an interview with its "creator" as a way to illustrate how stations such as KTVX promote sponsored content without being upfront about the sponsorship, essentially passing off advertising as news.

[32][33] The station's signal is multiplexed: In early 2008, KTVX carried "TheHive TV" on its second digital subchannel, which featured locally produced programs by Salt Lake City area residents and sports.

[35] The schedule resembled a public access cable channel; however, because the subchannel had to conform to FCC content guidelines, externally produced programs were approved by the station before they were broadcast.

KTVX extends its coverage throughout the entire state of Utah plus parts of Arizona, Colorado, Idaho, Nevada and Wyoming using a network of more than 100 community-owned translators listed below.
