Polyphony Digital
Originally a development group within Sony Computer Entertainment's Japan Studio known as Polys Entertainment,[2][3] after the success of Gran Turismo in Japan, they were granted greater autonomy, reestablished as an individual company and renamed themselves Polyphony Digital.In 2006, Polyphony released Tourist Trophy, in an attempt to bring the realism of Gran Turismo to motorcycle racing.The S-Tune was later sold in real life by NISMO (NISSAN MOTORSPORT) as a tuning package for existing owners.In 2007, they were contracted to design the multifunction display on the new Nissan GT-R,[7] which displays performance information such as G-forces, acceleration opening, brake pedal pressure, steering angle, an "optimal gearshift map," to emphasize economical vehicle operation.When Nissan was looking for a company to develop the GT-R's user-friendly 'multi-function meter', the carmaker says Polyphony was the obvious choice because of the simple menu systems applied to video games such as Gran Turismo.
