I came up with the concept of playing games on a standard TV set or TV monitor in September of 1966. The idea was to make an alternate, interactive use of tens of millions of home TV sets then in homes world-wide. The final equipment we built at Sanders Associates in 1967 (the "Brown Box") was licensed to Magnavox in 1970 and appeared as the Odyssey 1TL200 on the market in the US in May of 1972. Approximately one-hundred-thousand of these video game systems were sold that year by Magnavox. There was invention, development of the idea, marketing of the idea and follow through to see it into significant production.
