KAUT-FM

KAUT-FM (93.3 FM) is a commerical radio station in Flagstaff, Arizona and is owned by iHeartMedia. Its studios are located in the iHeartMedia Flagstaff Towne Centre building at 670 Campus Heights St, and its transmitters are located at the former building housing Taft American Radiocasters' HQ at Avocet Ave. KAUT-FM carries an adult hits format branded as "Austin FM", which serves as a rival to Sparknet's Jack FM service.

Austin functions similar to Jack, who is the mascot for all Jack FM stations. However, Austin's lines are created using a realistic text to speech program known internally as "Clear Channel's Computerized Audio Voice Emulator" or CAVE for short.

As KPHF-FM
On February 4, 1965, KAUT-FM launched as KPHF-FM. When it launched, it was owned by the Meredith Coporation who also owned sister stations, KPHF-AM and KPHF-TV. Initally when it launched it served as a simulcast of KPHF-AM, with both stations carrying the CBS radio network. But by 1971, the station would split off from its simulcast and became a Top 40 station. In 1973, Meredith would sell its Flagstaff based assets to Koplar Communications. Both KPHF-AM and KPHF-FM are the only radio stations owned by Koplar.

93 Taffy
In 1974, a year after Koplar purchased the station from Meredith, the station went under a major rebrand. The station changed its call-letters to KTAF, and its branding to 93 Taffy. Despite those, the station retained its Top 40 format. Around the exact same time, the station aired ads featuring their logo at the time (a literal taffy bar in red candy packaging with the text 93 Taffy put in a bold font), with most of the ads ending on the taffy bar opening to revealing a red taffy bar followed by the bar getting a bite. These ads are still symonous with the station to this day and in fact during the 2005 format change, physical versions of the 93 Taffy bar were sold.

In 1978, Koplar would sell both KKNX (the former KPHF-AM) and KTAF to an indepedent consortium owned by Taft Broadcasting, American Media (later known as Chancellor broadcasting) as well as a bunch of local Flagstaff based companies known as Taft/American Radiocasters.

The Ozone
Following heavy competiton with then-recent Top 40 station KRIT-FM in 1986, the station started to fall in the ratings and as such on April 19, 1988, KTAF would abandoned its Top 40 format and switched to an active rock format. The station would rebranded to KOOO with its branding being "The Ozone 93.3", the station's call-letters are in-fact based on the branding (the chemical formula of ozone gas is O3 or triple O).
