Sonic the Hedgehog

Sonic the Hedgehog is a video game series and media franchise created by the Japanese developers Yuji Naka, Naoto Ohshima, and Hirokazu Yasuhara for Sega. The franchise follows Sonic, an anthropomorphic blue hedgehog with supersonic speed, who battles the mad scientist Doctor Eggman and his robot army. The main Sonic the Hedgehog games are platformers mostly developed by Sonic Team; other games, developed by various studios, include spin-offs in the racing, fighting, party, and sports genres. The franchise also incorporates printed media, animations, films, and merchandise. Naka, Ohshima, and Yasuhara developed the first Sonic game, released in 1991 for the Sega Genesis, to provide Sega with a mascot to compete with Nintendo's Mario. Its success helped Sega become one of the leading video game companies during the fourth generation of video game consoles in the early 1990s. Sega Technical Institute developed the next three Sonic games, plus the spin-off Sonic Spinball (1993). A number of Sonic games were also developed for Sega's 8-bit consoles, the Master System and Game Gear. After a hiatus during the unsuccessful Saturn era, the first major 3D Sonic game, Sonic Adventure, was released in 1998 for the Dreamcast. Sega exited the console market and shifted to third-party development in 2001, continuing the series on Nintendo, Xbox, and PlayStation systems. Takashi Iizuka has been the series' producer since 2010. Sonic's recurring elements include a ring-based health system, level locales such as Green Hill Zone, and fast-paced gameplay. The games typically feature Sonic setting out to stop Eggman's schemes for world domination, and the player navigates levels that include springs, slopes, bottomless pits, and vertical loops. Later games added a large cast of characters; some, such as Miles "Tails" Prower, Knuckles the Echidna, and Shadow the Hedgehog, have starred in spin-offs. The franchise has crossed over with others in games such as Mario & Sonic, Sega All-Stars, and Super Smash Bros. Outside of video games, Sonic includes comic books published by Archie Comics, Fleetway Publications, IDW Publishing, and DC Comics; animated series produced by DIC Entertainment, TMS Entertainment, Genao Productions, and Netflix; a live-action film series produced by Paramount Pictures; and toys, including a line of Lego construction sets. Sonic the Hedgehog is Sega's flagship franchise, one of the bestselling video game franchises, and one of the highest-grossing media franchises. Series sales and free-to-play mobile game downloads totaled 1.77 billion as of 2024. The Genesis Sonic games have been described as representative of the culture of the 1990s and listed among the greatest of all time. Although later games, such as the 2006 game, received poorer reviews, Sonic is influential in the video game industry and is frequently referenced in popular culture. The franchise is known for its fandom that produces unofficial media, such as fan art and fan games.

History

1990–1991: Conception and first game

By 1990, the Japanese video game company Sega wanted a foothold in the video game console market with its 16-bit console, the Sega Genesis. Sega's efforts had been stymied by the dominance of Nintendo; the Genesis did not have a large install base and Nintendo did not take Sega seriously as a competitor. Sega of America CEO Michael Katz attempted to challenge Nintendo with the "Genesis does what Nintendon't" marketing campaign and by collaborating with athletes and celebrities to create games. These efforts did not break Nintendo's dominance, and Katz was replaced by Tom Kalinske, formerly of Mattel. Sega president Hayao Nakayama decided Sega needed a flagship series and mascot to compete with Nintendo's Mario franchise. Nintendo had recently released Super Mario Bros. 3, at the time the bestselling video game ever. Sega's strategy had been based on porting its successful arcade games to the Genesis; however, Nakayama recognized that Sega needed a star character in a game that could demonstrate the power of the Genesis's hardware. An internal contest was held to determine a flagship game, with a focus on the American audience. Among the teams working on proposals were artist Naoto Ohshima and programmer Yuji Naka. The gameplay of Sonic the Hedgehog (1991) originated with a tech demo created by Naka, who had developed an algorithm that allowed a sprite to move smoothly on a curve by determining its position with a dot matrix. Naka's prototype was a platform game that involved a fast-moving character rolling in a ball through a long winding tube. Sega management accepted the project, and the designer Hirokazu Yasuhara joined the team.

The focus shifted to the protagonist, who Sega hoped could become its mascot. The protagonist was initially a rabbit able to grasp objects with prehensile ears, but this proved too complex for the hardware. The team moved on to animals that could roll into a ball, and eventually settled on Sonic, a teal hedgehog created by Ohshima. Naka's prototype was expanded with Ohshima's character design and levels conceived by Yasuhara. Sonic's color was chosen to match Sega's cobalt blue logo, and his red and white shoes were inspired by the cover of Michael Jackson's 1987 album Bad. His personality was based on then-Governor of Arkansas Bill Clinton's "can-do" attitude. The antagonist, Doctor Eggman, was another character Ohshima had designed for the contest. The team thought the abandoned design was excellent and redesigned it as a villain. The team took the name Sonic Team for the game's release. Sonic's first appearance came in Sega AM3's racing game Rad Mobile (1991) five months before the release of Sonic the Hedgehog, as an ornament hanging from the driver's rearview mirror. The Sonic developers let AM3 use Sonic because they were interested in making him visible to the public. According to Mark Cerny, who worked in Tokyo as an intermediary between the Japanese and American Sega offices, the American staff felt that Sonic had no appeal. Although Katz was certain that Sonic would not be popular with American children, Kalinske arranged to place Sonic the Hedgehog as the pack-in game with the Genesis. Featuring speedy gameplay, Sonic the Hedgehog received critical acclaim. It greatly increased the popularity of the Sega Genesis in North America, credited with helping Sega gain 65% of the market share against Nintendo.
