The first consumer video game was the arcade video game Computer Space in 1971. The first video game prototypes in the 1950s and 1960s were simple extensions of electronic games using video-like output from large, room-sized mainframe computers. Video games are also classified into a wide range of genres based on their style of gameplay and target audience.

More recently, the video game industry has expanded onto mobile gaming through mobile devices (such as smartphones and tablet computers), virtual and augmented reality systems, and remote cloud gaming. Video games are typically categorized according to their hardware platform, which traditionally includes arcade video games, console games, and computer (PC) games the latter also encompasses LAN games, online games, and browser games. Most modern video games are audiovisual, with audio complement delivered through speakers or headphones, and sometimes also with other types of sensory feedback (e.g., haptic technology that provides tactile sensations), and some video games also allow microphone and webcam inputs for in-game chatting and livestreaming. A video game or computer game is an electronic game that involves interaction with a user interface or input device (such as a joystick, controller, keyboard, or motion sensing device) to generate visual feedback from a display device, most commonly shown in a video format on a television set, computer monitor, flat-panel display or touchscreen on handheld devices, or a virtual reality headset.
