Sony Computer Entertainment

The PlayStation 2 is the best-selling video game console of all time.

Sony Computer Entertainment is best known for producing the popular line of PlayStation consoles. The line grew out of a failed partnership with Nintendo. Originally, Nintendo requested for Sony to develop an add-on for its console that would play Compact Discs. In 1991 Sony announced the add-on, as well as a dedicated console known as the "Play Station". However, a disagreement over software licensing for the console caused the partnership to fall through. Sony then continued the project independently.
Launched in 1994, the first PlayStation gained 61% of global console sales and broke Nintendo's long-standing lead in the market. Sony followed up with the PlayStation 2 in 2000, which was even more successful. The console has become the most successful of all time, selling over 150 million units as of 2011^[update]. Sony released the PlayStation 3, a high-definition console, in 2006. It was the first console to use the Blu-ray format, although its expensive Cell processor made it considerably more expensive than competitors Xbox 360 and Wii. Early on, poor sales performance resulted in significant losses for the company, pushing it to sell the console at a loss. The PlayStation 3 sold generally more poorly than its competitors in the early years of its release but managed to overtake the Xbox 360 in global sales later on. It later introduced the PlayStation Move, an accessory that allows players to control video games using motion gestures.
Sony extended the brand to the portable games market in 2005 with the PlayStation Portable (PSP). The console has sold reasonably, but has taken a second place to a rival handheld, the Nintendo DS. Sony developed the Universal Media Disc (UMD) optical disc medium for use on the PlayStation Portable. Early on, the format was used for movies, but it has since lost major studio support. Sony released a disc-less version of its PlayStation Portable, the PSP Go. The company went on to release its second portable video game system, PlayStation Vita, in 2011 and 2012. Sony launched its fourth console, the PlayStation 4, on 15 November 2013, which as of March 1 2015 has sold 20.2 million units.
On 18 March 2014, at GDC, President of Sony Computer Entertainment Worldwide Studios Shuhei Yoshida announced their new virtual reality technology dubbed Project Morpheus for PlayStation 4. The headset, still in prototype form, will bring VR gaming and non-gaming software to the company's new console.
