NEC

Background
NEC Corporation (日本電気株式会社, Nippon Denki Kabushiki-gaisha) is a Japanese information technology and electronics corporation, headquartered in Minato, Tokyo. Their products range from information technology and network solutions products, to various consumer electronics such as personal computers, televisions, mobile phones, office facilities and video game consoles (PC Engine/TurboGrafx-16 and PC-FX). Originally branded as Nippon Electric Company, Limited, they changed to the NEC name in 1983. The company has been the biggest PC vendor in Japan since the 1980s after the launch of the PC-8000 series in 1979 - later followed up by the PC-8800 series in 1981 and the PC-9800 next year, with the PC-9800 series being supported until 2003. Once Japan's major electronics company, NEC has largely withdrawn from manufacturing since the beginning of the 21st century.
