Ken Kutaragi (久夛良木 健) is a Japanese engineering technologist and businessman.
He is the former chairman and CEO of Sony Interactive Entertainment (SIE), the video game division of Sony Group Corporation, and current president and CEO of Cyber AI Entertainment.
He is known as "The Father of the PlayStation", as he oversaw the development of the original console and its successors and spinoffs, including the PlayStation 2, PlayStation Portable, and the PlayStation 3.
1970
Eventually, in fact, his love of electronics led to him enrolling in University of Electro-Communications, where he acquired an Electronics degree in the 1970s.
Immediately after graduation, Kutaragi began working for Sony in their digital research labs in the mid-1970s.
Although at the time it was considered a radical decision, Kutaragi felt that Sony was on the "fast track".
He quickly gained a reputation as an excellent problem solver and a forward-thinking engineer, earning that reputation by working on many successful projects, including early liquid crystal displays (LCDs) and digital cameras.
1989
In 1989, he was watching his daughter play a Famicom and realized the potential that existed within video games.
At that particular time, Sony's executives had no interest in video games.
Thus, when Nintendo expressed the need for a sound chip for its upcoming new 16-bit system, Kutaragi accepted the offer.
Working in secret, he designed the chip, the SPC700.
When they found out, Sony's executives were furious.
Only with Sony CEO Norio Ohga's approval was Kutaragi able to complete the chip and keep his job.
Even while working with Nintendo, within Sony, gaming was still regarded as a fad.
Despite this hostile atmosphere to video games, Kutaragi managed to persuade Ohga into working with Nintendo to develop a CD-ROM add-on for the Super NES which would be released alongside a Sony branded console which could play both Super NES cartridges and CD games.
These efforts resulted in a device called the "Play Station".
Eventually, the partnership between Sony and Nintendo faltered due to licensing disagreements, but Kutaragi and Sony continued to develop their own console.
Kutaragi later recalled staying up all night working on the console design for several nights in a row "because our work was so interesting."
Despite being considered a risky gamble by other Sony executives, Kutaragi once again had the support of Ohga and several years later the company released the original PlayStation.
The success of the PlayStation led to him heading up the development of successor consoles, the PlayStation 2 and PlayStation 3.
The commercial success of the PlayStation franchise makes Sony Computer Entertainment the most profitable business division of Sony.
Despite being an upstart in the console market against veterans Nintendo and Sega, the first PlayStation displaced them both to become the most popular console of that era.
The PlayStation 2 extended Sony's lead in the following generation, at one point holding a 65% market share with 100 million units shipped.
1997
In 1997 Kutaragi was appointed CEO of Sony Computer Entertainment America, and accordingly moved to California.
Since 1997, Kutaragi had been favoured to become the next Sony president.
He enjoyed a close relationship with Ohga.
2003
Ohga's successor Nobuyuki Idei promoted Kutaragi to Deputy Executive President, Sony-Global chief operating officer, and Vice-Chairman in 2003.
2004
Kutaragi was recognized by many financial and technological publications for this success, most notably when he was named one of the 100 most influential people of 2004 in TIME magazine and the "Gutenberg of Video Games".
2006
On 30 November 2006, Kutaragi was replaced as president of Sony Computer Entertainment by Kazuo Hirai, the President of SCE America.
In addition to other management changes, Kutaragi was promoted to chairman of SCEI, and retained his position as chief executive officer of the group.
2007
He departed Sony in 2007, a year after the PlayStation 3 was released.
He had also designed the sound processor for the Super Nintendo Entertainment System.
With Sony, he designed the VLSI chip which works in conjunction with the PS1's RISC CPU to handle the graphics rendering.
Kutaragi was born in Tokyo, Japan.
His parents, although not wealthy by Japanese standards, still managed to own their own business, a small printing plant in the city.
As Kutaragi grew into childhood, they actively encouraged the young boy to explore his mechanical abilities in the plant, and he worked after school there.
Aside from his duties in his parents' factory, Kutaragi was a studious, high-level student; he was often described as a "straight-A student."
Kutaragi always had the desire to "tinker", often taking apart toys as a child rather than playing with them.
This curiosity carried from childhood, leading him as a teenager to learn the intricacies of electronics.
On 26 April 2007, it was announced that Kutaragi would retire and instead take up the role of Honorary Chairman.
