Magnavox Odyssey

The Magnavox Odyssey is a home video game console made by Magnavox in 1972. It is the first video game console ever made. It is part of the Magnavox Odyssey series.
The console could only display three square dots on the screen, and they could be moved with two controllers. To get a different game, you had to put a sheet of plastic on the TV screen and insert a card into the console that matches the number. It has no switch. The games start automatically if the console is powered.
