KCNS is a digital television station in San Francisco, California, in the United States, owned by NRJ TV, LLC. It carries programming from MundoFox on its main channel, and programming from Sino TV and Saigon TV on its subchannels. The station operates on 39 digital, covering the San Francisco Bay Area. The station will continue to use channel 38 as its virtual channel through the use of PSIP.
Channel 38 originally signed on the air on December 1, 1968 as KUDO-TV. The station initially broadcast financial programming in the mornings and early afternoons. The station also aired movies at night. The station went dark on October 3, 1971. On October 4, 1971, the Faith Center (owned by Eugene Scott) acquired the station for a cheap price and returned it to the air as KVOF-TV and remained broadcasting for 15 more years, carrying Dr. Gene Scott's "University Network" 24 hours a day. However, the station, along with sister stations KHOF-FM (now KKLA) in Los Angeles and KHOF-TV (now KPXN) in San Bernardino, California, lost its FCC license after Faith Center refused to disclose its private donor records to the FCC.
The current KCNS license began broadcasting on January 6, 1986 as KWBB, and was located on San Bruno Mountain. The station shared a building on Radio Road with KTSF, but could not continue with that arrangement. The licensee, West Coast United Broadcasting, and Dr. Gene Scott entered into an agreement, making available the original KVOF broadcasting facilities, in exchange for continuing Dr. Scott's night time programming. The new licensee ran infomercials and other programming during the day.
The station was sold to Global Broadcasting Systems and changed its call sign to KCNS. The station switched to Chinese and Filipino programming, with studios at the Hamms Building in San Francisco. In addition, the power was increased to five megawatts, and the transmitter moved to Sutro Tower on August 7, 1989, becoming the last analog television station to move there.
On January 5, 1998, KCNS switched to the Shop at Home Network, which brought the station to their home shopping programming. This lasted until June 21, 2006, when the Shop at Home's parent, The E. W. Scripps Company, suspended its operation. KCNS switched to Jewelry Television, and two days later, it started broadcasting a mixture of both networks, after Jewelry Television bought Shop at Home and resumed its operation.
On September 26, 2006, Multicultural Television announced it was buying KCNS from Scripps, as part of a deal to buy all of Scripps' Shop at Home channels for $170 million.  Multicultural closed on KCNS and the Cleveland and Raleigh stations on December 20, 2006. On January 14, 2007, KCNS ended its simulcast of Shop at Home and switched to educational and informational programming on early weekday mornings and infomercials the rest of the day. On KCNS began broadcasting Chinese language programming in Mandarin and Cantonese, under the "Sino TV" (華語電視) banner daily from 6:00pm to 12:00am, including news programs in both Mandarin and Cantonese.
Financial difficulties and sale to NRJ TV 
After Multicultural ran into financial problems and defaulted on its loans, KCNS was placed into a trust; in 2011, the station, along with WMFP in Boston, was sold to NRJ TV (a company unrelated to European broadcaster NRJ Radio). The sale was consummated on May 13, 2011. A one-third equity stake in NRJ TV is held by Titan Broadcast Management, which also operates KTNC-TV; Titan had already managed KCNS for some time prior to the sale.
Conversion to all digital 
KCNS turned off its analog signal on UHF channel 38 on February 17, 2009. The station now broadcasts only in digital on UHF channel 39, however, through the use of PSIP, digital tuners will still receive KCNS on channel 38 as a virtual channel.
