The first Oreo cookie was made in 1912 at the original Nabisco bakery in New York City (the factory is present day Chelsea Market).
Two flavors originally debuted in 1912, original and lemon meringue.
The origin of the name Oreo is unknown, but the leading theory is that the name was derived from the French word "Or", meaning gold (the early packaging was gold tin).
The first Oreo cookie was sold in Hoboken, NJ.
The cookie-to-creme ratio of an original Oreo cookie is 71% to 29%.
Over the years it has gone through several name changes:
In 1950, they created their very first advertising slogan, “Oh!, Oh! Oreo!”
Double Stuf Oreos were introduced in 1974.
Big Stuff Oreos were introduced in 1987, and were about 10 times larger than a regular Oreo. They were discontinued in 1991.
They became kosher in 1998.
50% of all Oreo eaters pull apart their cookies before eating them. Also, women twist them open more often than men.
In 1998, they introduced Oreo'Os cereal.
It is the world's best-selling cookie.
