KSTS

KSTS (channel 48) is a television station licensed to San Jose, California, United States, serving as the San Francisco Bay Area outlet for the Spanish-language network Telemundo. It is owned and operated by the network's Telemundo Station Group division (itself a subsidiary of NBCUniversal).

Under common ownership with NBC outlet KNTV (channel 11) and regional sports networks NBC Sports Bay Area and NBC Sports California, both KSTS and KNTV share studio facilities on North 1st Street in the North San Jose Innovation District; KSTS's transmitter is located on Mount Allison, and two of its subchannels are also broadcast from the KNTV tower on San Bruno Mountain.

KSTS was established in 1981 to provide subscription television service in the South Bay and Santa Clara Valley. The STV programming ended in 1983, and the station mostly became noted for specialty programming about business and computers as well as some ethnic programs. Telemundo purchased the station in 1987, giving the Bay Area a second station focusing on Spanish-language programming and a second choice for Spanish-language local news.

On March 29, 1978, the Federal Communications Commission (FCC) granted National Group Television a construction permit to build a new television station on channel 48 in San Jose. The permit took the call letters KQWT before becoming KSTS on January 2, 1979. John Douglas, the principal owner of National Group Television, attempted for more than a year to secure network affiliation for channel 48, but neither CBS nor NBC wanted to cannibalize their San Francisco affiliates. The station first signed on the air on May 31, 1981, as an independent station. The station's commercial programming included business programs, including a local program called Business Today, as well as old off-network shows. More daytime hours were filled by the then-new Financial News Network after it launched in November 1981.

At night, the station originally carried subscription television programming supplied by Satellite Television & Associated Resources (STAR TV) of Santa Monica; STAR had acquired the franchise from Universal Subscription Television three months prior to launch, a factor that delayed the new station's launch. STAR, which was not ready even after the delayed launch, bought the Super Time STV service on KTSF and relaunched it as STAR TV that September; the company promised to simulcast its STV programs on both stations for a year. Channel 48 broadcast its first subscription programs on November 8. The service ended in June after STAR became unable to pay KSTS; the loss of this revenue prompted the cancellation of Business Today and several layoffs. It would be replaced by a unique STV offering known as International Network Television, which consisted of three program tiers: two hours a night of Japanese-language shows, another two hours of Chinese-language programming, and a late-night adult film block. This generated enough business to allow the station to rehire two previously laid off employees.

The STV service, with just 3,000 subscribers in February 1983, ended on September 1. The station then added Chinese-language shows in prime time and additional brokered programming, including several shows on the young computer industry. The Thursday night Affordable Computer Hotline, channel 48's highest-rated show, was one of three devoted to the topic and cemented KSTS's place as "The Computer Connection". The station also rebroadcast the 1984 shareholders meeting of Apple Computer, where the Macintosh was introduced, as the company had been unable to accommodate all those who wanted to attend. However, when must-carry provisions were struck down, KSTS disappeared from several San Francisco-market cable systems; the manager of Viacom Cablevision systems in Marin County said that channel 48 had "phenomenally low ratings". The vast majority of its programming continued to be related to business and computing, as well as sports, wine, and photography, passions linked to its upscale audience. Further, the station aired foreign-language programming in Filipino and Vietnamese, among others, from independent producers.

In 1987, after several members of National Group Television desired to sell, Douglas sold KSTS to Telemundo Group, Inc., which operated the fledgling Telemundo Spanish-language network, for $17 million. At the insistence of network executive Paul Niedermayer, who had been instrumental in the 1985 launch of KVEA in the Los Angeles area, the network bypassed KCNS channel 38 to buy the station in San Jose, which at the time was home to 35 percent of the Hispanics in the Bay Area. The station, however, was not Spanish around the clock even after the sale. As late as 1990, locally produced programs in Portuguese and Persian were airing on KSTS. An effort at regional expansion began in 1990 when K15CU "KCU", a KSTS translator, began broadcasting in Salinas.

In October 1990, half of KSTS's 18 employees went on strike in protest of low pay and poor working conditions. The week-long strike, which resulted in temporary suspensions of the station's 6 p.m. newscast and the outright cancellation of its 11 p.m. news, resulted in the station staff unionizing with the International Brotherhood of Electrical Workers and agreeing to a contract in 1992.
