CNN — A snack-food icon turned 102 Thursday.
Oreo cookies first hit grocery stores back in 1912.
The first cookie was sold in Hoboken, New Jersey.
Back then, the cookies were sold by weight, not the same-size packages you see on the shelves now.
Today, Oreos are sold in more than 100 countries around the world.
Kraft foods says the cookie is one of its billion-dollar brands, generating about $1.5 billion dollars in revenue every year.
