NEC (Nippon Electric Company; 日本電気株式会社) are a Japanese electronics firm, specializing in IT services and products. Before its merger with fellow Japanese electronics company Renesas in 2010, it was one of the largest semiconductor companies in the world, ranked #1 from the 1980s to 1991, #2 from 1992 to 1999 (surpassed by Intel), and in the top ten during the 2000s. It was responsible for a number of parts used in Sega console and arcade hardware.
NEC had multiple divisions involved with video games: NEC Home Electronics (produced computers, consoles, and games), NEC Avenue (produced games) and NEC Interchannel (produced games).
