The first game in the franchise was released on June 23, 1991 in order to provide Sega with a mascot to rival Nintendo‘s flagship character Mario (see 1991 in video gaming). Since then, Sonic has become one of the world’s best-known video game characters, with his series having sold 45 million copies. In 2005, Sonic was one of the first game character inductees into the Walk of Game, alongside Mario and Link. Artist Naoto Ōshima, designer Hirokazu Yasuhara and programmer Yuji Naka are generally credited with the creation of the character, a blue 15-year-old anthropomorphic hedgehog, who has the ability to run faster than Mach 1. This is a major part of the gameplay of the series.
