The Microvision was designed by Jay Smith, the engineer who would later design the Vectrex gaming console. The Microvision's combination of portability and a cartridge-based system led to moderate success, with Smith Engineering grossing $15 million in the first year of the system's release. However, very few cartridges, a small screen, and a lack of support from established home video game companies led to its demise in 1981.[6] According to Satoru Okada, the former head of Nintendo's R&D1 Department, the Microvision gave birth to the Game & Watch after Nintendo designed around Microvision's limitations.[7]
