After the successful release of the original Ralph Baer-designed Magnavox Odyssey in 1972, the Odyssey 100 was released as its successor in 1975 (model no. YF7010). The Odyssey 100 featured Black & White graphics, two games (tennis and hockey), internal sound, manual scoring, and three control knobs for each player.
jussi, not the first one:-) This credit should go to Ralph Baer. It is his "Brown Box" that lead to the Magnavox Odyssey, which then became the first official home video game console.
