Sega's major mascot is as familiar to gamers as he is to everyday folks. Sonic the Hedgehog made his introduction to the world in his 1st official game back on June 23, 1991. Since then, the "Blue Blur" has made several appearances in even more video games, spawned a bunch of television shows, made his appearance during the Macy's Thanksgiving Day Parade and popped up opposite his 90's gaming rival Mario in Super Smash Bros. Brawl. With more than 80-million total copies sold of his numerous video games, it's safe to say that Sonic's career has been a plentiful one. Today (June 23, 2014), Sonic officially turns 23 years old. It's time to celebrate Sega's main star with 23 celebratory photos of the fastest hedgehog of them all.
