Ken Kutaragi, the man responsible for Sony’s dominance of the console game market, stepped down today as chairman and CEO of Sony Computer Entertainment, Inc. With Kutaragi’s leadership, Sony’s PlayStation console became the must-have game system of its time, outselling the Sega Saturn and Nintendo 64 on its way to household domination. Kutaragi also enjoyed much success with the PlayStation 2, but has had to endure production problems and some bad press with its third incarnation, the PlayStation 3.
