A home video game console is a video game console that is designed to be connected to a display device, such as a television, and an external power source as to play video games. While initial consoles were dedicated units with only a few games fixed into the electronic circuits of the system, most consoles since support the use of swappable game media, either through game cartridges, optical discs, or through digital distribution to internal storage.
