Nintendo System Development
Nintendo System Development Division, commonly abbreviated as Nintendo SDD and formerly known as Nintendo Network Business & Development (NBD), Nintendo Network Service Development (NSD), and Nintendo Special Planning & Development (SPD), was a Japanese division located in the Nintendo Research Institute in Kyoto, Japan, until it moved to the Nintendo Development Center, also in Kyoto. The division consisted of a single development team that focused on software and peripheral development. SDD was composed of two development departments with different duties: the Network Development & Operations Department, which handled Nintendo Network service programming, in cooperation with Nintendo Network Service Database, and the Environment Development Department, which developed Software Development Kits (SDKs), among other technologies. On September 16, 2015, SDD merged with Nintendo Integrated Research & Development (IRD), becoming the Nintendo Platform Technology Development.
