"Sonic the Hedgehog" is a video game starring the famous blue hedgehog from the Sega Genesis system. The game was developed by the sonic team and published by Sega in 1991. It was first released in North America in June 1991, followed by release in the PAL region and Japan in August 1991. Its popularity skyrocketed, and it is still one of the most popular video games to date.
It all started with a sketch created by Naoto Ohshima for the game's mascot. The idea of creating a speedy side-scrolling platformer was conceived by the team. The hedgehog's anthropomorphic design drew inspiration from several other popular cartoons and video games, including Super Mario, Mr. Needlemouse, and the Cat & Mouse series.
