Mario's time machine and Mario teach typing. The franchise has been divided into a variety of media, including television programs, films, comics and franchised goods.

Nintendo did not initially disclose Mario's full name. In an interview in 1989, although it hinted at the title of the Mario Bros. series, it was said that it was not "Mario Mario.". The first notable use of Mario Mario was in the 1993 live action movie adaptation. This approach is used again in Prima's two official strategic guides, Mario Party 2 in 2000 and Mario and Luigi: superstar saga in 2003. In 2012, after Charles martinet announced Mario as his "Mario Mario" at the San Diego animation show next month, Satoru Iwata said he had no last name, and Miyamoto agreed with him next month. Two months after Iwata's death in July 2015, Miyamoto changed his position on the 30th anniversary of the founding of the Super Mario Brothers in September 2015, confirming that his name was indeed Mario Mario.
