## History

### 1935 to 2000
Fujitsu was established on June 20, 1935, as Fuji Telecommunications Equipment Manufacturing, a spin-off of the Fuji Electric Company, itself a joint venture between Furukawa Electric and Siemens. It is one of the oldest operating IT companies, predating Hewlett-Packard. In 1954, Fujitsu manufactured Japan's first computer, the FACOM 100 mainframe, followed by the transistorized FACOM 222 in 1961 and the FACOM230 "5" Series in 1968, marking third-generation computers. The company also produced minicomputers, small business computers, servers, and personal computers like the FM-8, FM-7, and FM-Towns.

In 1955, Fujitsu founded the football club Kawasaki Frontale, now a J. League team. In 1967, the company officially changed its name to Fujitsu. In 1971, Fujitsu signed an OEM agreement with Canada's Consolidated Computers Limited to distribute the Key-Edit data entry product, leading to later associations with ICL and Gene Amdahl. In 1986, Fujitsu and Queen's University Belfast established a joint venture, Kainos, a software company. In 1990, Fujitsu acquired 80% of UK-based ICL for $1.29 billion and launched a new series of mainframe computers that were the fastest in the world at that time. In 1991, it acquired a majority stake in Russian company KME-CS. In 1992, Fujitsu announced a joint-venture plant in Punjab, India, for telephone switchboards and introduced the world's first 21-inch full-color plasma display. In 1993, Fujitsu formed a flash memory joint venture with AMD, called Spansion. From 1989 to 1997, Fujitsu built the FM Towns PC variant, and in 1993 released the FM Towns Marty gaming console. In 1997, Fujitsu acquired the remaining 58% of Amdahl Corporation and a 30% stake in GLOVIA International. In 1999, Fujitsu and Siemens merged their European computer operations into Fujitsu Siemens Computers.

### 2000 to 2024
In April 2000, Fujitsu acquired the remaining 70% of GLOVIA International. In 2002, ICL was rebranded as Fujitsu. In 2004, Fujitsu lost a class action lawsuit over defective hard disk drives and acquired the Australian subsidiary of Atos Origin. In 2007, Fujitsu signed a £500 million, 10-year deal with Reuters Group to outsource its IT department, and established an offshore development centre in Noida, India. In 2009, Fujitsu sold its HDD business to Toshiba.

In 2010, Fujitsu introduced the PRIMEHPC FX10 supercomputer. In 2011, it developed the K computer, which was the fastest supercomputer in the world at the time, with a performance of 10.51 petaflops. In 2014, Fujitsu launched the PRIMEHPC FX100. In 2020, Fujitsu completed the Fugaku supercomputer, which topped the TOP500 list in June 2020 and November 2020, with a performance of 442 petaflops. Fugaku is used for AI research, including [machine-learning](https://www.wikiprompt.org/wiki/machine-learning) and [deep-learning](https://www.wikiprompt.org/wiki/deep-learning) applications.
