Nintendo's transition into a gaming powerhouse was driven by employee Gunpei Yokoi, who joined the company in 1965.

From Toys to Digital Gaming
Before focusing on video games, Nintendo experimented with various ventures, including taxi services and instant noodles. Yokoi’s first major success was the 1966 Ultra Hand toy, which sold 1.4 million units. By the late 1970s, Nintendo shifted toward the video game market, launching home consoles and a coin-operated games division.
Lateral Thinking with Withered Technology
Yokoi pioneered a design philosophy called 'lateral thinking with withered technology,' which involves repurposing proven, affordable hardware for new applications. By collaborating with Sharp, Nintendo utilized existing calculator technology—specifically LCD screens and button cell batteries—to create the first Game & Watch title, Ball, in 1980. This approach allowed the company to produce 59 titles by 1991.
Lasting Impact on Handheld Design
The Game & Watch series sold over 43 million units worldwide and introduced design elements still used today, such as the D-pad and the clamshell format. According to the late Nintendo president Satoru Iwata, the success of these devices was essential for the eventual development of the Game Boy and Nintendo DS systems.
