Early years (2003-2006)

KZNS-FM is considered a "move in" station. On June 11, 2003, the unbuilt station was licensed as KTPM, originally located in Franklin, Idaho, close to the border between Idaho and Utah.^[2] At first, it was only a construction permit granted by the Federal Communications Commission (FCC), not actually on the air. Even before signing on, the station received FCC permission to move into the lucrative Salt Lake City radio market, from a location about 40 miles east of the city.

On August 10, 2005, the station, still not on the air, changed its call sign to KFMS. The station was sold to Three Point Media for $1.5 million, with the potential to profit from its pending move into Utah.^[3]

Talk (2005-2006)

In September 2005, the station signed on with a mostly-syndicated talk format. The lone local host was Tom Barberi.^[4]

Christian music (2006-2008)

On September 3, 2006, now licensed to Coalville, Utah, began broadcasting from Humpy Peak.^[5] On September 5, 2006, the station became KOAY and branded itself as "The Oasis," carrying a Christian Contemporary music format.

Active rock (2008-2010)

On September 9, 2008, the station changed to active rock and became "The Blaze," with the call letters becoming KZZQ.^[6] "The Blaze" had previously been located on 94.9 with the call sign KHTB, which subsequently became the call sign for a new active rock station in Provo, called "94.9 Z-Rock" (now Top 40-formatted KENZ). Reportedly, "The Blaze" had almost been shut down, but was able to continue, using the "Blaze" moniker because its owner, Citadel Broadcasting, failed to acquire the naming rights.^[7] "The Blaze" was one of three active rock radio stations in Salt Lake City, along with "Z-Rock" and KBER.

Rockin' hits (2010)

In January 2010, due to poor ratings (possibly as a result of competition against Z-Rock), "The Blaze" changed to what it called a "Rockin' Hits" format. However, this new format was met with even poorer ratings and negative response from the station's longtime listeners. A tribute concert for the "Blaze" by local artists took place shortly after the format flip.

Active rock (2010-2011)

On December 1, 2010, morning host Roger "Big Rog" Orton spent his shift protesting the station's new format by playing active rock songs. This protest was met with positive response from listeners, and the station received many supportive phone calls, song requests, e-mails, and Facebook messages. Several Facebook fan pages showing support for The Blaze also appeared and hundred listeners signed the radio station's van, which was spray-painted white to act as a petition for the station to return to the active rock format. The Blaze returned to playing active rock shortly afterwards.^[8]

Sports (2011-present)

In 2011, the station was acquired by the Larry H. Miller Communications Corporation. Miller owned a chain of car dealerships around Utah and the Western United States, and also owned the Utah Jazz basketball team. His goal was to own the radio stations that broadcast his team's games, running an all-sports format including shows discussing the Jazz.

On July 7, 2011, at Midnight, KZZQ changed its format to sports, simulcasting KZNS (1280 AM) as "The Zone". On July 15, 2011. KZZQ changed its call letters to KZNS-FM. On May 23, 2012, KZNS-FM relaunched as "Fox Sports Radio 97.5" with programming primarily from Fox Sports Radio. In 2013, KZNS-FM resumed simulcasting KZNS, once again as "The Zone." KZNS-AM-FM air mostly local sports shows on weekdays, and carry Fox Sports Radio nights and weekends. On April 13, 2021, it was announced that KZNS-FM and sister station KZNS-AM had been sold to Ryan Smith, who had recently purchased the Utah Jazz from the Larry H. Miller estate.^[9] On September 30, 2021, Bonneville International Corp. announced that KSL radio would be taking over day to day operations of KZNS AM/FM, which will allow select Utah Jazz games to be simulcast on KSL-AM 1160 and KSL-FM 102.7.^[10] Gordon Monson and Austin Horton were among the long time employees of The Zone who were dismissed as a result of KSL assuming operations of KZNS.^[11] Although KSL radio is responsible for overseeing daily operations of KZNS, Ryan Smith dba Jazz Communications LLC retains ownership of both 1280 AM and 97.5 FM according to the FCC database. The Zone's website at 1280thezone.com is now a dead link. The stations can now be streamed at kslsports.com/thezone/.
