Sonic the Hedgehog is a media franchise created and produced by Sega. It is primarily a video game franchise, centering on a series of speed - based platform games. Sonic, the protagonist, is an anthropomorphic blue hedgehog with supersonic speed, capable of reaching the speed of sound. Typically, Sonic — usually along with some of his friends, such as Tails, Amy, and Knuckles — must stop antagonist Doctor Eggman's plans for world domination. The first game in the series, released in 1991, was conceived by Sega's Sonic Team division after Sega requested a mascot character. Its success spawned many sequels and helped Sega become one of the leading video game companies during the 16-bit era of the early 1990s. While the first Sonic games were side - scrolling platform games, later games expanded into other genres, such as Mario & Sonic at the Olympic Games. The series and its spin - offs had sold over 89million physical copies by March 2011, and grossed over by 2014. As of 2018, the series has shifted 800million units, including free - to - play mobile game downloads. The franchise has also been spun out into other media, including cartoons, anime, and a comic book series recognized as the longest running based on a video game by Guinness World Records.
