A video game is a game that involves interaction with a user interface to generate visual feedback on a video device. The word video in video game traditionally refers to a raster display device. However, with the popular use of the term "video game", it now implies any type of display device. The electronic systems used to play video games are known as platforms; examples of these are personal computers and video game consoles. The user interface normally used to manipulate video games is called a game controller, which varies across platforms. For instance, a dedicated console controller might consist of only a button and a joystick, or feature a dozen buttons and one or more joysticks.

Beyond the common element of visual feedback, video games have utilized other systems to provide interaction and information to the player. Chief examples of these are sound reproduction devices and an array of haptic peripherals. The history of video games traces back to 1948, where the idea of a video game was conceived and patented by Thomas T. Goldsmith Jr. and Estle Ray Mann. Later in 1971, Computer Space was released, the first commercially sold, coin-operated video game console. Nolan Bushnell and Ted Dabney are credited as its creators.
