Oreo is a brand of sandwich cookie consisting of two cocoa biscuits or cookie pieces with a sweet fondant filling. It was introduced by Nabisco on March 6, 1912, and through a series of corporate acquisitions, mergers and splits both Nabisco and the Oreo brand have been owned by Mondelez International since 2012.
