Sony entered the video game ring back in the 90's with the Playstation. The Playstation used CD's as opposed to cartridges (NIntendo 64) and provided better graphics then it's competitors (Sega Dreamcast, Nintendo 64, GameBoy Color). The Playstation had 3 different controllers that were officially released by Sony:
-The normal Playstation controller (D-pad, Start, Select, X, O, Triangle, Square, L1, L2, R1, and R2 buttons)
-The Dual Analog Playstation controller (Two analog sticks, D-pad, Start, Select, X, O, Triangle, Square, Analog on/off, L1, L2, R1, and R2 buttons)
-The Dualshock Playstation controller with two rumble motors (Large rumble motor, small rumble motor, dual analog sticks, Analog on/off,  Select, Start, X, O, Triangle. Square, L1, L2, L3, R1, R2, and R3 buttons)

In early 2000, Sony created it's next new system, the Playstation 2. The Playstation 2 had higher quality graphics, excellent space in the memory cards, and could be played online via dial-up. Then Sony released something to make the Playstation 2 even more amazing: The EyeToy. The EyeToy is a USB webcam-like camera that project you onto the screen of EyeToy games, and puts you into the game. It picks up your movement, and makes things happen on the game (I.E. Swinging your hand to pop a bubble in EyeToy Play 2). The Playstation 2 was re-designed into a smaller, more compact system later on in it's run. It held the title of the best selling system until the Nintendo DS systems stole it in 2010.

The Playstation 3 was Sony's third game console, and one to remember. It features wireless Bluetooth controllers, the ability to download classic PS1 games, and is capable to play against other people wordwide via Wi-Fi.
