Nintendo

Nintendo Co., Ltd. (任天堂株式会社) is a Japanese multinational consumer electronics and software company headquartered in Kyoto, Japan. Nintendo is the world's largest video game company by revenue. Founded on September 23, 1889, by Fusajiro Yamauchi, it originally produced handmade hanafuda playing cards. By 1963, the company had tried several small niche businesses, such as cab services and love hotels.

Abandoning previous ventures in favor of toys in the 1960s, Nintendo then developed into a video game company in the 1970s, ultimately becoming one of the most influential in the industry and Japan's third most-valuable company with a market value of over $85 billion.
