KVVC took to the air on January 9, 1948, licensed jointly to the cities of
Ventura and
Oxnard, California. The station became KBBQ by January 1973, featuring a
country format, along with
NBC Radio programming. On February 1, 1985, the call sign switched to KOGO and the format flipped to
adult contemporary music. As KOGO, the station changed hands twice. In July 1986, Forrest Radio sold KOGO and sister station
KBBY-FM to New York City-based ownership group Ventura Broadcasting Associates for $3 million. That same group sold the combo three years later to Buena Ventura Inc., headed by George Duncan, for $6.7 million. KOGO renamed itself KBBY after its FM counterpart on September 17, 1993; In December 1996, Buena Ventura Inc. sold the station, then using the KXSP calls and broadcasting in
Spanish, along with
KTND, to
Gold Coast Broadcasting for $2 million. The transaction split the station from its longtime combo partner KBBY-FM which later would be owned by
Cumulus Media. From 1998 to 2004, the station held the KUNX call letters and aired a Spanish-language talk format under the "Radio Unica" branding. For a brief period in early 2004, it was known as KKOM and broadcast content from The American Comedy Network. The former KUNX and KKZZ then exchanged frequencies, with the KKZZ call letters landing on 1590 AM on March 5 and KUNX's Spanish programming resurfacing on
1400 AM. On April 10, 2025, KVTA changed their format from news/talk to sports, branded as "Fox Sports 1590/97.9". ==References==
