In July 1995, KDFW replaced KDAF (channel 33) as the Fox affiliate for the Dallas-Fort Worth Metroplex, as a result of an affiliation agreement between Fox and New World Communications, who had purchased the station from Arygle Television in a group deal. This deal also sent its longtime CBS affiliation to Gaylord Broadcasting-owned KTVT. Around this time, the station also changed its branding to Fox 4 Texas, unifying its brand to be in line with the News 4 Texas title it had been using for its newscasts since 1990.

1996–1997

Around this time, the station's on-air brand was altered to simply Fox 4, which has remained in use ever since, concurrent with the re-titling of the station's newscasts as Fox 4 News, and also changing the names of its weather and sports branding to Fox 4 Weather and Fox 4 Sports; all three segment names have also remained in use ever since. New World was sold to the News Corporation (now 21st Century Fox) in 1997 and KDFW was placed under the control of Fox Television Stations.

This logo branding, currently in use by most of the Fox O&Os, is based on the Fox News logo; with their website names ("myfox(city name).com") based off of the domain for the social network Myspace, which former Fox parent News Corporation briefly owned.
