KSTS, virtual channel 48 (UHF digital channel 49), is a Telemundo owned-and-operated television station serving the San Francisco Bay Area that is licensed to San Jose, California, United States. The station is owned by the NBCUniversal Owned Television Stations subsidiary of NBCUniversal, as part of a duopoly with NBC owned-and-operated station KNTV (channel 11). The two stations share studios and offices located on North 1st Street in San Jose. KSTS's transmitter is located atop Mount Allison.
The station first signed on the air on May 31, 1981 as an independent station. It was owned by National Group Television, which was headed by N.J. Douglas. The station initially offered programming weekdays from 5 a.m. to 3 p.m. from the Financial News Network. From 3 p.m. to 7 p.m. weekdays and from noon to 4 p.m. weekends, the station ran off network shows from the 50's and early 60's such as Fury, Gentle Ben, Flipper, Batman starring Adam West, Danny Thomas Show, Jackie Gleason Show, low budget old movies, and other shows. Weekdays after 7 p.m. and weekends throughout much of the day, the station offered various types of brokered programming included foreign language shows, religious programs and some programming pertaining to technology. The station branded under the slogan "Your Computer Connection". KSTS was also the only station to broadcast the introduction of Apple's Macintosh personal computer at the company's 1984 Annual Shareholders Meeting. Beginning in the fall of 1981, KSTS carried the subscription television service Star TV, featuring recent movies, after 7 p.m. daily. By 1983, they were carrying subscription TV after 12 noon on weekends. By 1983, the off network shows were dropped for more brokered programming. That year, the station ran various brokered programming weekends from 5 a.m. to noon and from 3 to 6 p.m. weekdays. Financial News remained weekdays till 3 p.m.
NightMusic premiered in August 1984, a three hour weekly live show that featured music videos and comedy. Hosted by John Ward with co-host Brian Leonard NightMusic aired from 9PM to 12M every Saturday for a year and a half and became a cult favorite. Chris Isaak was a frequent guest and Translator once served as the house band.
In 1984, Star TV began winding down operations due to the fact cable penetration eliminated the need for Subscription TV opver the air. In January 1985, the station partnered with two other Spanish-language independent stations, 47 WNJU New York City and 51 WCSV Miami to carry about eight hours a day of Spanish programming (which replaced Star TV programming locally) on weekday evenings, forming a network known as NetSpan; later in the year, other stations such as KVEA Los Angeles and 26 WCIU Chicago (which lost affiliation with Spanish International Network gradually joined these the network. Spanish programming gradually increased, on weekends especially and brokered shows gradually were dropped. By 1986, KSTS was running Spanish programming for about half of its broadcast day on weekdays but the entire day weekends. Later that year the Financial News Network programming ended and the station became the entire broadcast day. NetSpan was relaunched as Telemundo in mid-1987. By then, the station was running the network's programming about 16 hours a day. Telemundo bought the station outright later that year, at which time KSTS began carrying Telemundo programming full-time. Initially, KSTS was targeted at the San Jose/Silicon Valley region, but after converting to the Spanish language format, it changed its focus towards the entire San Francisco Bay Area.
In 2000, as a result of its corporate takeover of Telemundo, NBC became the owner of KSTS; it then became a sister station to KNTV (channel 11), which also originally targeted San Jose, after NBC bought that station from Granite Broadcasting Corporation in 2002. The station moved into all-digital broadcast center housed alongside KNTV in 2004.
The station's digital channel is multiplexed:
|Channel||Video||Aspect||PSIP Short Name||Programming|
|48.1||1080i||16:9||KSTS-HD||Main KSTS programming / Telemundo|
KSTS shut down its analog signal, over UHF channel 48, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 49, using PSIP to display KSTS' virtual channel as 48 on digital television receivers.
KSTS presently broadcasts five hours of locally produced newscasts each week (with one hour each weekday; the station does not produce any newscasts on Saturdays and Sundays). In 1988, KSTS launched its news department with the debut of a half-hour 6 p.m. newscast, which was originally co-anchored by Celina Rodriguez and Dante Betteo. The program proved successful, which resulted in the station later adding a half-hour 11 p.m. newscast. On February 27, 2012, KSTS became the first Spanish language television station in the Bay Area to begin broadcasting its local newscasts in high definition.
