In 1994, KTSP changed its call letters to KSAZ for "The Spirit of AriZona". By the end of that same year, KSAZ ended its long-time CBS affiliation and became an Fox affiliate following a deal between the network and station's owner, New World Communications to affiliate most of its stations with the then-fledging network. CBS then went to independent and initial CBS affiliate KPHO-TV as KSAZ took Fox from what would later be ABC affiliate KNXV-TV.
On July 31, 2006, KSAZ adopted a new graphics package, first seen on sister station WTVT in Tampa-St. Petersburg, and is currently in use by most Fox O&Os. The branding 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 was briefly owned by Fox's then parent company News Corporation (then 21st Century Fox, now Fox Corporation). In this logo, the distance between the numbers "1" and "0" have been widened.
