Nintendo was assembled in 1889. The company first started as a Hanafuda (playing cards) company, then, on about 1966, the company started producing video games.
According to Wikipedia:
In 1966, Nintendo moved into the Japanese toy industry with the Ultra Hand, an extendable arm developed by its maintenance engineer Gunpei Yokoi in his free time. Yokoi was moved from maintenance to the new "Nintendo Games" department as a product developer. Nintendo continued to produce popular toys, including the Ultra Machine, Love Testerand the Kousenjuu series of light gun games. Despite some successful products, Nintendo struggled to meet the fast development and manufacturing turnaround required in the toy market, and fell behind the well-established companies such as Bandai and Tomy.
