The series' first installment was 1983's Mario Bros., although Mario made his first appearance in 1981's arcade game Donkey Kong and had already been featured in several games of the Donkey Kong and Game & Watch series. The Mario games have been developed by a wide variety of developers, including Nintendo, Hudson Soft, and AlphaDream. Mario games have been released almost exclusively for Nintendo's various video game consoles and handhelds, from the third generation onward.
