While its two main rivals in the gaming industry, Microsoft and Sony, rely almost solely on third-party software for their consoles, a significant proportion of Nintendo games are created and developed in-house. The company is known to have created some of the most popular video game franchises in the industry, such as Mario and The Legend of Zelda, and it also is a part owner of The Pokémon Company. One of the newest games in the Mario franchise, Super Mario Odyssey, has sold over 10 million copies as of March 2018.
The Nintendo Wii (succeeded by the Wii U in 2012) is the company’s most popular brand product. As of its 2017 fiscal year, Nintendo has sold altogether 115.2 million Wii and Wii U consoles worldwide. However, Wii's success has come to witness an end, being replaced by that of Nintendo's newest console, the Switch, which sold 15.5 million units in the year following its release in March of 2017.
