Hardware

Sony Computer Entertainment produces the PlayStation family of video game hardware consisting of consoles and handhelds. Sony's first wide home console release, the PlayStation (codenamed PSX during development, currently PSone), was initially designed to be a CD-ROM drive add-on for Nintendo's Super Nintendo Entertainment System (a.k.a. Super Famicom in Japan) video game console, in response to Sega's Mega-CD. When the prospect of releasing the system as an add-on dissolved, Sony redesigned the machine into a stand alone unit. The PlayStation was released in Japan on December 3, 1994 and later in North America on September 9, 1995. Currently the highest selling home console of all time, SCE's second home console, the PlayStation 2 (PS2 or PSX2) was released in Japan on March 4, 2000, and later in North America and Europe in October and November 2000, respectively. The PS2 is powered by a proprietary central processing unit, the Emotion Engine, and was the first video game console to have DVD playback functionality included out of the box. Initially, the system was criticized for its complex development environment, due mainly to the proprietary hardware included, however despite these complaints the PlayStation 2 received widespread support from third party developers throughout its lifespan on the market. Today it has sold up to 150 million units world wide.

The PlayStation Portable (PSP) is SCE's first foray into the small handheld console market, which was and to this date still is dominated by Nintendo. Its development was first announced during SCE's E3 conference in 2003, and it was officially unveiled during their E3 conference on May 11, 2004. The system was released in Japan on December 12, 2004, in North America on March 24, 2005 and in Europe and Australia on September 1, 2005. The console has since seen two major redesigns, with new features including a smaller size, more internal memory, a better quality LCD screen and a lighter weight. A new design, the PSP Go, was released on October 1, 2009 for North America and Europe and on November 1, 2009 for Japan. It has a 3.8" LCD which slides up to reveal the main controls. The PSP Go is 45% lighter and 56% smaller than the original PSP and does not support UMD. The device does support Bluetooth and will be completely digital meaning all media must be downloaded or transferred to the device which has 16 GB of internal flash memory.

The newest home console in the PlayStation family, as well as Sony's entry in the seventh-generation of consoles, the PlayStation 3 (PS3) was launched in November 2006. It utilizes a unique processing architecture, the Cell microprocessor, a proprietary technology developed by Sony in conjunction with Toshiba and IBM. The graphics processing unit, the RSX 'Reality Synthesizer', was co-developed by Nvidia and Sony. Several variations of the PS3 have been released, each with slight hardware and software differences, each denoted by the varying size of the included hard disk drive.

The newest handheld console in the PlayStation family is the PlayStation Vita. It is the successor to the PlayStation Portable as part of the PlayStation brand of gaming devices. It was released in Japan and parts of Asia on December 17, 2011 and in Europe, Australia and North America on February 22, 2012. Internally, the Vita features a 4 core ARM Cortex-A9 MPCore processor and a 4 core SGX543MP4+ graphics processing unit, as well as LiveArea software as its main user interface, which succeeds the XrossMediaBar.
