The PlayStation 3 (officially abbreviated as 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. The PlayStation 3 competes with Microsoft's Xbox 360 and Nintendo's Wii as part of the seventh generation of video game consoles. 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.
PlayStation 3 Slim This refers to the "slim" version of the PS3. This model had 2 USB Ports, no PS2 emulation support and 802.11b/g wireless.
PlayStation 3 Super Slim In September 2012, Sony announced that a new slimmer PS3 redesign (CECH-4000) was due to be released in late 2012 and that it would be available with either a 250 GB or 500 GB hard drive.
