KJLA (channel 57) is a Spanish-language religious independent television station licensed to Ventura, California, United States, serving the Los Angeles area.
In 1994, Walter Ulloa purchased Costa de Oro Television and KSTV-TV, intending to increase its transmitting power and extend its signal to better reach to the Los Angeles area.
However, although Ventura is considered part of the Los Angeles market, Federal Communications Commission (FCC) rules at the time placed KSTV-TV within the Santa Barbara–Santa Maria–San Luis Obispo market, similar to the situation of KADY-TV channel 63 (now KBEH-TV) in Oxnard, California which became Santa Barbara's UPN affiliate when the network launched in January 1995.
Unable to get cable coverage in the Los Angeles area, on November 1, 1995, KSTV switched to an English-language format and became the WB affiliate for the Santa Barbara market.
The improved signal helped the station to obtain must-carry status on most cable providers in western Los Angeles County in February 1998.
The station changed its call letters to KJLA on July 20, 1998, to further reflect its intentions to serve the Los Angeles market.
In November 2001, the Simi Valley translator was moved to Mount Wilson and started broadcasting to Los Angeles as KSMV-LP on channel 33.
An FCC spokesperson stated that channel sharing would allow broadcasters to "[take] advantage of the incentive auction’s once-in-a-lifetime financial opportunity", while still maintaining its ability to run over-the-air television programming.
