Oreo (/ˈɔːrioʊ/ ⓘ; stylized in all caps) is an American brand of sandwich cookie consisting of two cocoa biscuits with a sweet fondant filling. Oreos were introduced in 1912 by Nabisco, and the brand has been owned by Mondelez International since its acquisition of Nabisco in 2012. Oreo cookies are available in more than 100 countries. Many varieties of Oreo cookies have been produced, and limited-edition runs have become popular in the 21st century.
Oreos are an imitation of the Hydrox chocolate cream-centered cookie introduced in 1908, but it outstripped Hydrox in popularity so largely that many believe Hydrox is an imitation of Oreo. Oreo has been the highest-selling cookie brand in the world since 2014.
