The PlayStation 3 (marketed as PLAYSTATION 3 until September 2009 and officially abbreviated to PS3) is the third home video game console produced by Sony Computer Entertainment, and the successor to the PlayStation 2 as part of the PlayStation series. A major feature that distinguishes the PlayStation 3 from its predecessors is its unified online gaming service, the PlayStation Network, which contrasts with Sony's former policy of relying on video game developers for online play. Other major features of the console include its robust multimedia capabilities, connectivity with the PlayStation Portable, and its use of a high-definition optical disc format, Blu-ray Disc, as its primary storage medium. The PS3 was also the first Blu-ray 2.0-compliant Blu-ray player on the market.
