KISS-FM is the brand name of a Top 40 music format heard on FM radio stations in many cities in the United States and overseas.

The process of bringing the KISS format to cities beyond Los Angeles was begun by Randy Michaels' Jacor Communications before Clear Channel bought it in 1999.

[4] Michaels, later Clear Channel's chief executive officer, and brand manager Todd Shannon likened the KISS model to McDonald's.

[4] Similarly, the top five most-played artists for the week ending October 20, 2002, on Chicago's KISS station (WKSC-FM) included Cam'ron, Eminem, and Justin Timberlake, while the same list at Dallas' KISS station (KHKS) featured Kelly Clarkson, John Mayer, and Creed.

[6] On July 24, 2006, Statesville, North Carolina's heritage country station WFMX was moved to Clemmons, a suburb of Winston-Salem, and flipped to soft R&B as WMKS, the second "Kiss" to feature a soft-R&B format, after then-WKUS in Norfolk, Virginia.

On December 15, 2008, Clear Channel reached an agreement to acquire five CBS Radio stations, one of them being KBKS (106.1 Kiss FM) in Seattle.

In return, CBS would acquire two Clear Channel stations in Houston as an effort to expand its focus on the larger markets.

The Kiss FM name has been widely used both by licensed and pirate stations in several European countries including Ireland, the United Kingdom, France, Italy, Poland, Ukraine, Romania, Moldova, Iceland, Greece, Spain, Sweden and Berlin (Germany).

On August 29, 2013, all four "EZ Rock"-branded Hot AC stations owned and operated by Rogers, CJMX-FM Sudbury, CKGB-FM Timmins, CHUR-FM North Bay, and CHAS-FM Sault Ste.

The 95.3 frequency was subsequently reclaimed by the Australian broadcasting regulator and auctioned off for $106 million in exchange for allowing Midwest to extend its service area into the Blue Mountains of New South Wales.

The Australian Radio Network (ARN) launched the KIIS brand in Australia in January 2014, after rebranding their failing Sydney station Mix 106.5.

[13] ARN, partially owned by Clear Channel at the time, poached top rating breakfast duo Kyle and Jackie O from rival 2Day FM, and launched the new positioning and music format on January 20, 2014.

In the first survey following the switch, Kyle & Jackie O added 6 percentage points to the timeslot to become equal first FM breakfast with sister-station 101.7 WSFM.

[15] At the same time, the station announced a new national drive show featuring former Nova 100 breakfast team Dave "Hughesy" Hughes and Kate Langbroek.
