Consoles
PlayStation

Sony's first foray into the video game market, the PlayStation (formerly PSX, currently called PS one), was initially set to be an add-on for Nintendo's Super Nintendo Entertainment System and Super Famicom video game consoles as an answer to Sega's Sega CD. When the prospect of releasing the system as an add-on dissolved, Sony transformed it into the PlayStation video game console. The PlayStation was released in Japan on December 3, 1994 and later in North America on September 9, 1995. The system was widely popular and quickly became one of the best selling home consoles, only behind Nintendo's NES/Famicom.
PlayStation 2
Sony's sixth generation console, the PlayStation 2 or PS2 was released in Japan on March 4, 2000 and later in North America on October 26, 2000. The PS2 is powered by a proprietary CPU, called the Emotion Engine and is the first video game console to have DVD playback functionality. Some game developers complained that the PlayStation 2 was too hard to develop for, and others also claimed that the PS2 was not as powerful as its competitors. Despite these complaints, the PlayStation 2 had widespread support from third party developers and was very successful in the marketplace. It placed first in number of units sold in its generation, with Microsoft's Xbox placing second and Nintendo's GameCube third.
PSX
In December 2003 Sony upgraded the PlayStation 2 adding DVD burning and a hard drive with video recording functionality. The upgraded system was renamed the PSX (an acronym formerly used to represent the original PlayStation). The PSX has extensive media connectivity with the PSP. It is an expensive luxury device (approximately US$700). Due to its lack of popularity, it was never released outside of Japan [1].
PlayStation 3

The PlayStation 3 is Sony's next-generation video game console. The system was unveiled on May 16, 2005 at a press conference prior to the 2005 E³ event. The PS3 is powered by a CPU called the Cell developed by IBM, Toshiba, and Sony themselves. The console has many innovative features such as Blu-ray disc technology, a tilt sensing controler, and high-end multimedia interfaces such as HDMI which is fully capable of 1080p resolution. The PlayStation 3 is backward compatible with both the PlayStation 2 and the original PlayStation. Sony defines the machine as "The Super Computer Entertainment Device". It is due to launch November 11th in Japan and six days later, on November 17th, in Europe, North America and Australia.
Linux
In 2002, Sony released the first useful operating system for a video game console, after the Net Yaroze experience. The kit turned the PlayStation 2 into a full fledged computer system running Linux. The mix of hardware and software cost approximately US$149 at launch.
According to recent speeches by CEO Ken Kutaragi, the PlayStation 3 will receive another Linux distribution pre-installed on hard drives to better control online and multimedia capabilities.
In November 2005 Sony formed the Linux Alliance with IBM and Philips.
