March 6th is National Oreo Cookie Day in the United States.

Needless to say, this is definitely one of the more commercial days around, given that the Oreo is a trademark of Nabisco. The Oreo Biscuit was first introduced by the National Biscuit Company - which later became Nabisco - back in 1912. It was originally launched as an imitation of another cookie produced by a competitor, the Hydrox of Sunshine. Today, it is the best-selling cookie brand in the United States.

The Oreo is classed as a sandwich cookie, as it consists of two wafers with a sweet crème filling. The wafers and filling can vary, but the most commonly recognised design is the two chocolate wafers. The cookie is distinctively decorated on the wafers, although the design has changed over the years. Some varieties of Oreo have even covered in dark or white chocolate. Other varieties have included ones with more filling, ones with thinner wafers, smaller varieties and other flavourings for the cookies and filling. The Oreo is popular with people who have dietary restrictions, such as vegans, as the filling does not use any animal products.
