Nintendo Entertainment Analysis and Development

Nintendo Entertainment Analysis and Development (Nintendo EAD), formerly Nintendo Research & Development 4 (Nintendo R&D4), was a division of Nintendo known for designing Mario games, although they have also worked on other series, such as The Legend of Zelda and Star Fox. The Chief Production Officer was Satoru Iwata, but the general managers are Shigeru Miyamoto and Takashi Tezuka. There is even a Nintendo character based off of this department named Mr. EAD.

On September 14, 2015, Nintendo announced plans to merge EAD and the game development arm of Nintendo SPD into a new division known as Nintendo Entertainment Planning and Development, effective September 16, 2015.
