To overcome this debacle, Sega of America president, Bernie Stoller urged the Sega’s head office in Japan to developed a sixth generation game console. Thus the initiative of developing the Dreamcast took place.  Two teams were assigned the task. One team was led by Hideki Sato and the other one was headed by Tatsuo Yamamoto. Both group used Hitachi SH4 processor. But Sato’s group selected VideoLogic PowerVR2 graphics processor while Yamamoto’s group chose 3dfx hardware for graphics. Ultimately Sega settled for PowerVR hardware. In 1999, after it’s release in US, over 400000 units were sold within 4 days.
