I came to like Jensen Huang's character, and bet everything on him, Shoichiro Irimajiri said in an interview. Shoichiro Irimajiri, former president of what is now Sega Co., said in a recent interview that he had decided to invest $5 million in then-fledgling U.S. chipmaker Nvidia in the late 1990s because he was impressed by the character of its CEO, Jensen Huang. Irimajiri, 86, was head of then-Sega Enterprises when he persuaded the company's top executives to rescue the struggling Nvidia, which has since become one of the world's biggest companies. "I came to like Jensen Huang's character, and bet everything on him," Irimajiri said in the interview. Sega contracted Nvidia to develop a graphics processing unit for the Dreamcast game console it was developing to compete with the PlayStation console released by then Sony Computer Entertainment.
