A video game console is a device that outputs a video signal or visual image to display a video game. The term "video game console" is used to distinguish a console machine primarily designed for consumers to use for playing video games in contrast to arcade machines or home computers. It includes home video game consoles, handheld game consoles, microconsoles and dedicated consoles.
Although Ralph Baer had built working game consoles by 1966, it was nearly a decade before Pong made them commonplace in home theaters. Through evolution over the years, game consoles have expanded to function as CD players, DVD players, web browsers, set-top boxes and more.
