History
Adult contemporary (1989-1992)
KISF signed on as KLTN with an adult contemporary format as "Lite 103.5" in February 1989. In January 1991, the station rebranded as "Magic 103.5" under new call sign KMMK.
Modern rock (1992-1998)
On May 22, 1992, the station changed its call sign to KEDG, and adopted a modern rock music format, branded as "The Edge".[1] The station debuted at #1 in the Las Vegas ratings and was influential in other stations nationwide flipping to the format. In 1996, KEDG gained a direct competitor as KFBI adopted a harder edged modern rock music format under the call sign KXTE.
R&B oldies (1998-1999)
On June 5, 1998, at Noon, KEDG flipped to urban oldies under the call sign KISF, and branded as "Kiss-FM".[2]
Spanish (1999-present)
In March 1999, Heftel Broadcasting Corporation (which eventually became Univision Radio and then Uforia Audio Network) acquired the frequency, and flipped 103.5 to Regional Mexican as "La Nueva 103.5", becoming the first Spanish FM radio station serving the Las Vegas Hispanic community.[3] On March 24, 2016, KISF rebranded as "Zona MX 103.5".
KISF was one of eighteen radio stations that TelevisaUnivision sold to Latino Media Network in a $60 million deal announced in June 2022, approved by the Federal Communications Commission (FCC) that November,[4] and consummated on December 30, 2022.[5] Under the terms of the deal, Univision agreed to continue programming the station for up to one year under a local marketing agreement.[4]
In June 2023, TelevisaUnivision turned over full operations of the three stations to Latino Media Network, making the Las Vegas market the second market from the company to turn over its operations from TelevisaUnivision, with the first one being the McAllen-Brownsville-Harlingen market in the spring of 2023.
