Nintendo Entertainment Analysis and Development
From the Super Mario Wiki
Nintendo Entertainment Analysis and Development (Nintendo EAD) 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 Software Planning & Development (Nintendo SPD) into a new division known as Nintendo Entertainment Planning and Development (Nintendo EPD), effective September 16, 2015.
