A visual guide to watch gaming's 40-year history


efore there were portable games, there were calculators. And somehow, those nearly ubiquitous calculating machines inspired the notion of not just portable computation, but a new way to pass the time: gaming on the go.

It was a calculator that became what many consider to be the first handheld gaming device: a low-fi drag racing game from Mattel. And a calculator game by Casio became the first popularized game watch creation.
