Nintendo Entertainment Analysis and Development is the largest division inside Nintendo. It was preceded by the Creative Department, a team of designers with an art background responsible for many different tasks, to which Shigeru Miyamoto and Takashi Tezuka originally belonged. Both developers currently serve as managers of the EAD studios and are credited in each game developed by the division, with varying degrees of involvement. EAD is best known for its work on games in the Mario, The Legend of Zelda, F-Zero, Star Fox, Donkey Kong, and Pikmin franchises. In 1997, Miyamoto explained that twenty to thirty employees were devoted to each EAD title during the course of its development.
