Department Global Entertainment. The studio has collaborated with several in-house Japanese studios as well as other American-based studios such as STI and Visual Concepts. Sonic Team are best known for the Sonic the Hedgehog series.
In 1990, Sega asked one of their departments to create a game with a character that was popular enough to rival Nintendo's Mario. What the group came up with was a speedy platformer with a new, fresh character called Sonic the Hedgehog. In 1991 AM8 took its name from its phenomenally successful Sonic the Hedgehog series and became Sonic Team. Sonic Team was headed by the famed video game designer and producer Yuji Naka. Under his leadership, Sonic Team has become a creative powerhouse in the video game industry.
