It was Uemura’s wife that named the system. In April, 1983, Uemura brought up the topic of the Gamecom at home. Uemura’s wife then said the following: “If it’s a domestic computer that’s neither a home computer nor a personal computer, perhaps you could say that it’s a family computer. In Japanese, ‘personal computer’ is shortened to ‘pasokon’, so why don’t you nickname it the ‘Famicom’?"
