Sonic the Hedgehog is the platform game that launched the career of Sonic the Hedgehog and Sonic Team. It was the first in Sega's Sonic the Hedgehog series. Sonic was intended to Sega's mascot to compete with Nintendo's Mario. The game and character were specifically designed to demonstrate the processing speed of the Sega Genesis.

This game was the first game to propel the Genesis into mass popularity in North America. After it was released, it eventually replaced Altered Beast as the bundled game with the console. The game featured many novel elements which contributed to its popularity and helped to promote the uptake of 16-bit consoles.

Sonic the Hedgehog added the element of speed to the standard platform formula and introduced other unique elements as well, such as the loops, springboards, hi-speed devices, and rings now permanently associated with the game series.

Since its release it has been ported to many other systems and compilations, including Sonic Jam, Sega Smash Pack: Volume 1, Sonic Mega Collection (and Sonic Mega Collection Plus) and, most recently, the Sega Genesis Collection. It is also available via the GameTap and Wii Virtual Console download services.
