Mario

Shigeru Miyamoto created Mario while developing Donkey Kong in an attempt to produce a best-selling video game for Nintendo; previous titles like Sheriff had not achieved the same success as titles like Pac-Man. Originally, Miyamoto wanted to create a video game that used the characters Popeye, Bluto, and Olive Oyl. At the time, however, Miyamoto was unable to acquire a license to use the characters (and would not until 1982), so he ended up making Jumpman (later known as Mario), Donkey Kong, and Pauline. In the early stages of Donkey Kong, Mario was unable to jump, and the focus was to escape a maze. However, Miyamoto enabled Mario to jump, saying "If you had a barrel rolling towards you, what would you do?"

                                      

Miyamoto originally named the character "Mr. Video", and he was to be used in every video game Miyamoto developed. According to a widely circulated story, during localization of Donkey Kong for North American audiences, Nintendo of America's warehouse landlord Mario Segale confronted his then-president Minoru Arakawa, demanding back rent. Following a heated argument in which the Nintendo employees eventually convinced Segale he would be paid, they opted to name the character in the game Mario after him.
