Nintendo System Development (often shortened to SDD), which was formerly known as Nintendo Special Planning & Development (abbreviated as SPD) until 2008, Nintendo Network Business & Development (abbreviated as NBD) until 2011, and Nintendo Network Service Development (abbreviated as NSD) until 2013, was a division of Nintendo based in Kyoto. The division was responsible for software and peripheral development such as StreetPass and the Nintendo eShop. It consisted of two departments: Network Development & Operations, responsible for Nintendo Network's programming, and Environment Development, responsible for Nintendo's software development kits and the online infrastructures; this department also had a group, Mechanical Design, dedicated to software for home consoles. It was merged with Nintendo Integrated Research & Development on September 16, 2015, forming Nintendo Platform Technology Development.
