The PlayStation is a home video game console developed and marketed by Sony Computer Entertainment. It was released in Japan on 3 December 1994, and most of the world in 1995. Sony began developing it after a failed venture with Nintendo to create a CD-ROM add-on in the early 1990s. The console was primarily designed by Ken Kutaragi and his team in Japan, while additional development was outsourced in the United Kingdom. An emphasis on 3D polygon graphics was placed at the forefront of the console's design. The PlayStation signalled Sony's rise to power in the video game industry. It received acclaim and sold strongly; in less than a decade, it became the first computer entertainment platform to ship over 100 million units. Its use of compact discs heralded the game industry's transition from cartridges. The PlayStation's success led to a line of successors, beginning with the PlayStation 2 in 2000. (Full article...)
