Every day for 100 days, Oreo has been posting a new image or ad as part of its "Daily Twist" campaign in print and social media.
The finale is next Tuesday (October 1), when that day's ad will be revealed in New York City's Times Square, based on customers' ideas and submissions.
Some of the Oreo promotions in this centenary year are taking the iconic cookie in distinctly different directions from its chocolate roots.
As an example, the new seasonal Halloween-themed version exclusive to Target stores, with "candy corn" flavor and icing, has received mixed reviews.
Still, this unusual twist on the traditional cookie is keeping the Oreo name in the spotlight and headlines! Happy birthday, Oreo.
