The low-power station was founded in 1989 as translator K24CM on channel 24, before changing from a translator to an LPTV as KSFV-LP in 1995, moving to channel 26 in 2001. On April 30 of that year, the station debuted Spanish-language programming targeted towards Central American immigrants. Sometime after that, the station moved to channel 6 to make room for KVCR-DT in San Bernardino, which had signed on its digital signal on channel 26. Because of this move, the station began marketing itself as an FM radio station (carrying a Spanish Religious service known as Guadalupe Radio), since the audio of analog TV channel 6 can be heard at the bottom of the FM radio dial at 87.75 MHz. The station received Class A status in 2009, as KSFV-CA.
On March 9, 2009, Venture Technologies announced that it had signed a leasing agreement with Mega Media Group to launch a Dance format on KSFV, thus ending the Spanish Religious format on the signal. Programming was to have begun on June 1, 2009, and it would have been patterned after Mega Media's New York City outlet WNYZ-LP and likewise, carry the "Pulse 87" brand.[2] However, Venture Technologies has notified Radio World that it would not take Mega Media's offer and Mega Media ceased operations in October 2009.[3]
After converting KSFV to digital, Venture Technologies maintained the channel 6 analog service by acquiring KZNO-LP in Big Bear Lake and moving Guadalupe Radio to the latter. As of July 13, 2021, analog channel 6 has been shut off per FCC notice.[4]
On June 25, 2024, KSFV-CD dropped Jewelry TV and became a MeTV Toonsowned-and-operated station on its main channel, with the station adding a third subchannel and moving Jewelry TV there.
