Based on the world record nomination from American Records Institute (AMRI) and Decision No. WK/USA.INDIA/728/2021/No.184, World Records Union (WorldKings) officially declared Magnavox Odyssey is the world’s first commercial home video game console on August 3, 2021.

The Magnavox Odyssey is the first commercial home video game console. The hardware was designed by a small team led by Ralph H. Baer at Sanders Associates, while Magnavox completed development and released it in the United States in September 1972 and overseas the following year. The Odyssey consists of a white, black, and brown box that connects to a television set, and two rectangular controllers attached by wires. 

It is capable of displaying three square dots and one line of varying height on the screen in monochrome black and white, with differing behavior for the dots depending on the game played. Players place plastic overlays on the screen to display additional visual elements for each game, and the one or two players for each game control their dots with the knobs and buttons on the controller in accordance with the rules given for the game.
