Around 1983/1984, in the wake of "Donkey Kong"'s commercial success, a game designed by Shigeru Miyamoto, Hiroshi Imanishi oversaw the creation of Research & Development No. 4 Department (commonly abbreviated to Nintendo R&D4), as a new development department dedicated to developing video game titles for dedicated consoles, complementing the other three existing departments in the Nintendo Manufacturing Division, green-lit by then-Nintendo president Hiroshi Yamauchi. Imanishi appointed Hiroshi Ikeda, a former anime director at Toei Animation, as general manager of the newly created department, and Miyamoto as its chief producer, who would later become one of the most recognized video game developers in the world. Nintendo also drafted a couple of key graphic designers to the department including Takashi Tezuka and Kenji Miki. With the arcade market dwindling, Nintendo R&D1's former focus, the department concentrated most of their software development resources on the emerging handheld video game console market, primarily thanks to the worldwide success of Nintendo's Game Boy. This catapulted the R&D4 department to become the lead software developer for Nintendo home video game consoles, developing a myriad of games for the Family Computer home console (abbreviated to Famicom, known as the Nintendo Entertainment System in North America, Europe, and Australia).
