Title: Game Boy family
Content:  Nintendo's Game Boy handheld was first released in 1989. The gaming device was the brainchild of long-time Nintendo employee Gunpei Yokoi, who was the person behind the Ultra Hand, an expanding arm toy created and produced by Nintendo in 1970, long before Nintendo would enter the video game market. Yokoi was also responsible for the Game & Watch series of handhelds when Nintendo made the move from toys to video games. When Yokoi designed the original Game Boy, he knew that to be successful, the system needed to be small, light, inexpensive, and durable, as well as have a varied, recognizable library of games upon its release. By following this simple mantra, the Game Boy line managed to gain a vast following despite technically

Content:  In 1988, Gunpei Yokoi and his team at Nintendo R&D1 conceived the Game Boy, the first handheld video game console to be compatible with interchangeable game cartridges. Nintendo released the Game Boy in 1989. In North America, the Game Boy was bundled with the popular third-party game Tetris after a difficult negotiation process with Elektronorgtechnica. The Game Boy was a significant success: in its first two weeks of sale in Japan, it sold out its initial inventory of 300,000 units, while in the United States, an additional 40,000 units were sold on its first day of distribution. Around this time, Nintendo entered into an agreement with Sony to

Content:  The early 1970s represented a watershed moment in Nintendo's history as it released Japan's first electronic toy—the Nintendo Beam Gun, an optoelectronic pistol designed by Masayuki Uemura. In total, more than a million units were sold. Nintendo partnered with Magnavox to provide a light gun controller based on the Beam Gun design for the company's new home video game console, the Magnavox Odyssey, in 1971. Other popular toys released at the time include the Ultra Hand, the Ultra Machine, the Ultra Scope, and the Love Tester, all designed by Yokoi. The Ultra Hand sold more than 1.2 million units in Japan. During the early 1970s, Nintendo began trading on the main section of the Osaka stock exchange and opened a new headquarters.
Title: Nintendo Research &amp; Development 1
Content:  In 1965, Nintendo, still primarily a hanafuda card manufacturer, hired Gunpei Yokoi, a newly-graduated electronics engineer. Yokoi was assigned to the manufacturing division to work on the assembly line machines used to manufacture its cards. In the following year, Hiroshi Yamauchi, president of Nintendo at the time, during a visit to the factory Yokoi was working at, took notice of a toy, an extending arm, that Yokoi had made for his own amusement during his spare time. As Yamauchi was looking to diversify the company's business far beyond its primary card business, Yokoi was ordered to develop the toy into a proper mass-market product for the 1966 holiday rush. The toy was launched as Ultra Hand and it was a huge success selling over 1.2 million units during its lifetime. Following that, Yokoi was assigned to work on other toys including the Ten Billion Barrel puzzle, a miniature remote-controlled vacuum cleaner called the Chiritory, a baseball throwing machine called the Ultra Machine, and a "Love Tester."

These devices had a much higher novelty value than traditional toys, allowing Nintendo to charge a higher price margin for each product. Yokoi went on to develop many other toys, including the Ten Billion Barrel puzzle, a baseball throwing machine called the Ultra Machine, and a Love Tester. Nintendo released the first solar-powered light gun, the Nintendo Beam Gun, in 1970; this was the first commercially available light-gun for home use, produced in partnership with Sharp. In 1972, Nintendo released the Ele-Conga, one of the first programmable drum machines. It could play pre-programmed rhythms from disc-shaped punch cards, which could be altered or programmed by the user, to play different patterns.
Title: History of Nintendo
Content:  During the 1960s, Nintendo struggled to survive in the Japanese toy industry, which was still small at this point, and already dominated by already well-established companies such as Bandai and Tomy. Because of the generally short product life cycle of toys, the company took the approach of introducing new products at a faster rate, marking the beginning of a major new era for Nintendo. In 1966, Yamauchi, upon visiting one of the company's hanafuda factories, noticed an extending arm, which had been made by one of their maintenance engineers, Gunpei Yokoi, for his own amusement. Yamauchi ordered Yokoi to develop it as a proper product for the Christmas rush. Released as the "Ultra Hand", it would become one of Nintendo's earliest toy blockbusters, selling over a million units. Seeing that Yokoi had promise, Yamauchi pulled him off assembly line work. 
Title: Game &amp; Watch
Content:   Game designer Gunpei Yokoi had been head of Nintendo's Research & Development division in the 1970s, designing physical toys and games until the 1973 oil crisis, after which the market waned for these products. At the same time, the first arcade and home video game consoles had been developed in the United States, and Nintendo had quickly caught onto this wave in Japan. While traveling on a Shinkansen (bullet train), Yokoi saw a bored businessman playing with an LCD calculator by pressing the buttons. Yokoi then thought of an idea for a watch that doubled as a miniature game machine for killing time. Later, he had been able to pitch the idea to Nintendo's president, Hiroshi Yamauchi, when Yamauchi requested him to chauffeur him to
