KOKO-FM originally signed on the air April 16, 1990,[3] as country station KTAA and was owned by Barnard Broadcasting A California Limited Partnership during the early 1990s. In the early 1990s, the station flipped to a short-lived hip-hop format as Jammin 94, before flipping to regional MexicanLa Fiesta. In 1997, the station was acquired by Hispanic Radio Enterprise Inc., and flipped to a rhythmic format as 94.3 The Party. In 1998, Art Laboe acquired the station and it was rebranded as Power 94, and later Hit Radio 94.3 in August 2001.[4] This was then followed by a rhythmic AC format.
On June 28, 2012, KOKO-FM flipped to classic hits.[5] On November 27, 2018, KOKO-FM again changed formats, this time to rhythmic oldies as Jammin' 94.3.[6]
Art Laboe died October 7, 2022, at age 97.[7] In July 2023, TED Broadcasting agreed to purchase KOKO-FM from the Art Laboe estate for $330,000.[8]
