Oreo

n. brand of chocolate sandwich cookie produced by Nabisco

Oreo is a trademark for a popular sandwich cookie manufactured by the Nabisco Corporation (National Biscuit Company). The current design consists of a sweet, white filling commonly referred to as 'cream' or 'creme', sandwiched between two circular chocolate wafers. Over 490 billion Oreo cookies have been sold since they were first introduced, making them the best selling cookie of the 20th century. Its most recent packaging slogan is "Milk's Favorite Cookie", which is a slight change from "America's Favorite Cookie."
