American television manufacturer Magnavox releases the world’s first home video game system, the Odyssey, based on the hardware of Ralph Baer’s Brown Box created at Sanders & Associates. The system includes not only two bulky controllers and six basic games, but colorful, semi-transparent overlays suitable for the two most common TV screen sizes and other playing pieces, such as cards and poker chips. Other games and a light gun accessory will be sold in 1973. Magnavox has been including the Odyssey in its in-person product demonstrations since spring 1972.
