Oreo 100th birthday. Celebrate the kid inside. 1912-2012. For our 100th birthday, Oreo is here to remind you and your family that there's a kid inside of each and every one of us who deserves to be set free every now and then. It's time to slow down. It's time to play. It's time to twist, lick and dunk your way to that carefree feeling of childhood. Come join us at oreo.com/birthday.
