The History of NEC Corporation

NEC Corporation is a global manufacturer and supplier of IT hardware and services, hailing from Japan and with its headquarters located in Minato, Tokyo. It has a broad range of products that it provides to a wide gamut of business spheres, from government agencies to large private business enterprises.

Known as the largest PC manufacturer in Japan since the home computer boom during the 1980s, it began life as the Nippon Electric Company Ltd. In 1983, it adopted the name known around the world today and it was a major player in the semiconductor market, breaking into the top 20 producers before it eventually amalgamated with Renesas Electronics a few years later.

Early History
The origins of this great company go back far further than most, as it was first established a staggering 120 years ago by Takeshiro Maeda and Kunihiko Iwadare, on August the 31st 1898. It moved into factories purchased from an existing electrical manufacturer of the time and it entered into the telephone market in the early 20th century.

The Booming 80s
NEC made its first significant move in the IT market, when in 1982, it produced the NEC µPD7710 digital signal processor, the very first of its kind. This was an innovation that resulted in part, from the establishment of NEC Semiconductors in 1981 and it was the first in a succession of new tech from the company.

Having launched the PC-8800 8-bit series in the same year, closely followed by the PC-9800 series in 1982, it would become a publicly floated enterprise on the Swiss stock exchanges. NEC would soon become the biggest name in PC production in Japan, obtaining a hugely dominant 80% share of the market.

Breaking the US
1984 is the year that NEC Information Systems entered the US IT hardware market, as it began the manufacturing of computer hardware. The V Series processor was launched in the same year and by 1986 NEC had demonstrated its SX-2 Supercomputer, which was the first to feature multiple processor cores.

Just a year later, NEC Technologies UK Ltd came into being and began manufacturing printers, early mobile phone technology, monitors for computers and video recorders.

Financial Crisis
The company had to shed 10,000 workers in 2009, as it had to consolidate its position during the financial crisis. Whilst its semiconductor business channels have been a little sluggish in recent years, it has been involved in some major projects in related fields, having been commissioned by the likes of Google, Singtel, and KDDI to create an undersea pipeline linking Japan and the US. A feat completed in 2016.

Whilst it may not have been the most influential company in the IT world in recent years, it still has a large market share, particularly in Japan, where it enjoys almost 25% of the business available.
