KFSF-DT, virtual channel 66 (UHF digital channel 34), is a UniMás owned-and-operated television station serving the San Francisco Bay Area that is licensed to Vallejo, California, United States. The station is owned by Univision Communications, as part of a duopoly with Univision owned-and-operated station KDTV-DT (channel 14). The two stations share studios located at the 50 Fremont Center building in San Francisco's Financial District, KFSF's transmitter is on Sutro Tower in San Francisco.

The station first signed on the air on November 25, 1986 as KPST-TV, carrying a combination of Asian programs and programming from the Home Shopping Network. It was founded by Silver King Broadcasting, the broadcasting arm of HSN. When Barry Diller bought the USA Network (and effectively HSN) in the mid-1990s, the company was renamed USA Broadcasting.

By the late 1990s, USA Broadcasting planned to switch its HSN stations to a general entertainment independent format, plans for KPST to switch had not been announced when USA put all its stations up for sale in 1999; The Walt Disney Company was originally the leading bidder for the stations, which would have made KPST a sister station to ABC owned-and-operated KGO-TV (channel 7), but Univision Communications outbid its competition in a close race. Once Univision completed the purchase of the USA Broadcasting, over a year after it was announced, the station became a charter affiliate of Univision's new secondary network Telefutura (which would later relaunch as UniMás in January 2013) on January 14, 2002, and accordingly had changed its call letters to KFSF.

Analog-to-digital conversion

KFSF shut down its analog signal, over UHF channel 66, on June 12, 2009, as part of the federally mandated transition from analog to digital television.[2] The station's digital signal remained on its pre-transition UHF channel 34, using PSIP to display KFSF's virtual channel as 66 on digital television receivers, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition.
