On August 29, 1996, at noon, KXEZ changed calls to KIBB and flipped to a dance-leaning rhythmic hot AC format, branded as "B100" ("The Rhythm of L.A."). The first song on KIBB was "You Dropped a Bomb on Me" by The Gap Band.
The move was to go after listeners who had become disenfranchised with the increasing hip-hop content at KPWR. The move also came about based on the instant success of WKTU in New York City, which debuted in February of that year. 
In 1997, Chancellor Media bought KIBB, added current songs to its playlist, and shifted directions to rhythmic contemporary hits. The slogan changed to "L.A.'s Hot FM".
The KIBB call sign was assigned to an adult hits station serving Wichita, Kansas, until May 2023, when it rebranded as Bob FM and took on the KBOB-FM call sign.
