Sonic the Hedgehog is the first release in the Sonic the Hedgehog series and was designed to be the mascot for Sega. Development for Sonic the Hedgehog began in 1990 when Sega president Hayao Nakayama instructed his development team to develop a mascot for the company. Prior to Sonic Sega was using Alex Kidd as their mascot but he was considered too similar to Nintendo’s mascot Mario and did not seem to have the same appeal to the gaming audience. Nakayama wanted a character as iconic as Mickey Mouse to compete with Nintendo who was dominating the market at the time.
