At the Consumer Electronics Show in June, 199 1, Sony announced that it would cooperate with Nintendo to launch a game console called PlayStation. Yoshiki Hayashi Kudo is in charge of this project. In fact, it is a SNES super game machine with a CD. Yoshiki Hayashi Kudo, from Sony's hardware engineering department, hopes to show the possibility of cooperation between Sony and the game industry through this game console. But one day later, Nintendo unilaterally tore up the contract and announced cooperation with Philips.
Sony put a lot of energy into this game console and even completed a prototype. Sony suggested that Nintendo distribute the royalties due to Sony from the sales of game discs, but Nintendo said: "We think these imposed fees are totally unacceptable." Although this angered Sony, it was unwilling to admit its complete failure. Gensonnie's Columbia Film Company still controlled the PlayStation business in Europe.
Since then, Sony has been committed to the game industry. In July of that year, Sony said it planned to sue Nintendo. At the same time, with the support of Kudo of Yoshiki Hayashi, some engineers from broadcasting field participated in the research and development of 3D graphics engine system. 1September, 1992, this European game publishing business machine made its first real-time 3D image demonstration. 1994, this machine was finally announced as PlayStation.
