The Microvision was a hand-held game console released by Milton Bradley Company in 1979. The Microvision was designed by Jay Smith who later went on the design the famous Vectrex. Microvision's combination of a cartridge-based system and portability would surely be a success. In the first year, $8 million was grossed making Smith Engineering a million dollar industry. But very few cartridges, a small screen, and no backing-up by a conventional console lead to its demise in 1981.
