"The Magnavox was the first video game console. Created in 1972 by Ralph Baer, which began working on it in 1966.
There were 27 games released in 12 different cartridges for this console, including some famous ones like Simon Says, Table Tennis, Volleyball and Shooting Gallery.
The operation of the Odyssey is very basic. Most of the games used special plastic overlays placed on the television screen to simulate the background graphics that the system could not draw. The Magnavox also didn't have a CPU. 330,000 units were sold."
