intro: The Oreo is turning 100! Get your glass of milk ready!
Created on March 6, 1912, in a National Biscuit Co. bakery in Manhattan, the sandwich cookie has come a long way from its first sale to a grocer by the name of S.C. Thuesen in Hoboken, N.J.
Now an international favorite, Oreos can be bought in more than 100 countries and rake in $1.5 billion in global annual revenues. More than 95 million cookies are sold each day.
Becky Tousey, Kraft Foods' corporate archivist -- aka "Oreo historian" -- said the brand's message had maintained the same theme in its advertising over the years.
"The focus of advertising was on the fun of eating Oreos, the fun of the parts of the Oreo," she told ABC News. "It has that theme of the enjoyment -- the twisting, the licking, the dunking. For me, as a historian, it's fun to see that thread throughout."
The cookie's popularity has endured through at least five design changes and the National Biscuit Co.'s name change to Nabisco and then eventual takeover by Kraft Foods.
"It's always been a top seller -- if not, the top seller for quite a few decades," Tousey said of the Oreo brand. "Even early on, it became clear to the National Biscuit Co. that it was one of its flagship brands and the company really supported it. ... [Oreo] has demonstrated decade after decade that it continues to endure."

text: Whether it's twisted and licked or simply dunked, the Oreo has hardcore fans.
The cookie currently has more than 25 million fans on its Facebook page and also has a street named after it -- Oreo Way -- in New York City.
The cookie, which takes 59 minutes to make, consists of 12 flowers, 12 dots and 12 dashes on each side. Each cookie has 90 ridges.
No one has been credited with coming up with the Oreo idea and there are many theories on the origins of the name. Tousey said that she believed the name came from combining the "re" in creme and the two "o's" in chocolate.
