KFTL was founded on April 25, 1986 with an original construction permit granted to National Innovative Programming Network. Initially assigned to Palo Alto and Los Altos, California, and given callsign K30BI, the station's construction permit was modified and extended several times. In August 1990, Channel America acquired the station, but sold it again in July 1992 to Polar Broadcasting, who finally licensed the station on May 3, 1994. By this time, the station had been assigned to San Francisco, Oakland and San Jose.
K30BI (referred to as "KBI-TV"), was formerly affiliated with The Box, a 24-hour-a-day music network, and aired classic television during the day. Eventually, the station changed affiliations to HSN. Its call letters were changed to KBIT-LP shortly after. The station also relocated to channel 28 to make way for KQED's digital signal on channel 30.
KBIT received Class A status on August 27, 2001, and received its current call sign in February 2004 after being taken over by Family Radio. Family Radio formerly used the call letters KFTL on analog channel 64 licensed to Stockton, which is now Telefutura network affiliate KTFK-DT.
KFTL flash cut to digital on June 27. Currently their analog programming is being transmitted on 1 sub-channel and a 2nd has a Home Shopping Network feed. The three translators have also all switched to digital.
Family Radio sold KFTL to LocusPoint Networks in November 2012.
