The PlayStation brand is a line of video game consoles created and developed by Sony Computer Entertainment, occupying the fifth, sixth, and seventh generations.
Distinguishing features Unlike its competitors, which largely use face buttons on their controllers denoted by letters (generally A, B, C, X and Y), PlayStation controllers uses shapes; namely ('Triangle'), ('Circle' or "O"), ('X' or 'Cross') and ('Square' or ' Box'). The Select button is a raised rectangular button while Start is a raised right-pointing triangle. It was the first controller design to feature 4 buttons on the top [L1, L2, R1, R2] (named by the side [L=Left, R=Right] and 1 or 2 [top or bottom] and commonly referred to as shoulder buttons). Beginning with the PlayStation 3, a 'PlayStation button' (featuring the incorporated PS logo and similar in function to the Xbox 360 "X" logo button) was added to the controller, in place of the 'Analog' button. The Analog button activated the analog sticks on the Playstation and Playstation 2 Dual Analog, Dual Shock and Dual Shock 2 controllers. On the Playstation 3 Sixaxis and Dual Shock 3 controllers they are either both in use and have different purposes. The PS button on the PS3 brings up the Playstation 3 home screen (similar to a PC "desktop" screen) while holding it down brings up system options (such as quit the game, change controller settings, turn off the system, and turn off the controller).
