Sonic Team is a Japanese video game development division of Sega.
The game was a major success, and started the long-running Sonic the Hedgehog franchise.
Sega's financial troubles led to several major structural changes in the early 2000s, the United Game Artists studio was absorbed by Sonic Team in 2003, and Sonic Team USA became Sega Studios USA in 2004.
In addition to the Sonic series, the company has developed other games for Sega, such as Nights into Dreams (1996) and Billy Hatcher and the Giant Egg (2003).
[1][2] The 1991 release of Sonic the Hedgehog is considered significant in video game history, as it increased the Sega Genesis's sales and Sega displaced Nintendo as the leading video game company.
