A console game is a type of video game consisting of images and often sounds generated by a video game console, which are displayed on a television or similar audio-video system, and that can be manipulated by a player. This manipulation usually takes place using a handheld device connected to the console, called a controller. The controller generally contains several buttons and directional controls such as analogue joysticks, each of which has been assigned a purpose for interacting with and controlling the images on the screen. The display, speakers, console, and controls of a console can also be incorporated into one small object known as a handheld game.
Console games usually come in the form of an optical disc, ROM cartridge, digital download or, in the case of dedicated consoles, stored on internal memory. The global console games market was valued at about $26.8 billion in 2018.
The differences between consoles create additional challenges and opportunities for game developers, as the console manufacturers (e.g. Nintendo, Microsoft, Sony, Sega, Atari) may provide extra incentives, support and marketing for console exclusive games. To aid development of games for consoles, manufacturers often create game development kits that developers can use for their work.
Early history of video games
The first console games were for the Magnavox Odyssey, released in 1972, and consisted of simple games made of three white dots and a vertical line. These hardware limitations, such as the lack of any audio capability, meant that developers didn't have freedom in the type of games they could create. Some games came packaged with accessories such as cards and dice to enhance the experience and make up for the shortcomings of the hardware.
The second generation of consoles introduced more powerful capabilities, less hardware limitations than the first generation, and coincided with the golden age of arcade video games. Developers had access to the console's basic graphical capabilities, allowing them to create sprites of their choosing and more advanced sound capabilities.
