In 1980, NEC created the first digital signal processor, the NEC µPD7710. NEC Semiconductors (UK) Ltd. was established in 1981, producing VLSIs and LSIs. NEC introduced the 8-bit PC-8800 series personal computer in 1981, followed by the 16-bit PC-9800 series in 1982. In 1983 NEC stock was listed on the Basel, Geneva, and Zurich, Switzerland exchanges. NEC quickly became the dominant leader of the Japanese PC industry, holding 80% market share. NEC changed its English company name to NEC Corporation the same year. NEC Information Systems, Inc. started manufacturing computers and related products in the United States in 1984. NEC also released the V-series processor the same year. In 1986, NEC delivered its SX-2 supercomputer to the Houston Advanced Research Center, The Woodlands, Texas. In the same year, the NEAX61 digital switching system went into service. In 1987, NEC Technologies (UK) Ltd. was established in the United Kingdom to manufacture VCRs, printers, and computer monitors and mobile telephones for Europe. Also that year, NEC licensed technology from Hudson Soft, a video game manufacturer, to create a video game console called the PC-Engine (later released in 1989 as the TurboGrafx-16 in the North American market). Its successor, the PC-FX, was released in Japan in 1994. While the PC-Engine achieved a considerable following, it has been said that NEC held a much stronger influence on the video game industry through its role as a leading semiconductor manufacturer than through any of its direct video game products. NEC USA, Inc. was established in 1989 as a holding company for North American operations.
