Oreos continue to be a blessing and a curse. A blessing because they are completely delicious and a curse because they keep coming out with new flavors like brownie batter, s'mores, red velvet, and now, key lime pie with graham cracker cookies. Like the other "limited edition" novelty flavors, these pie-flavored cookies come in a package that's only 10.7 ounces, slimming down the package rather than cookie. The cookies are currently available at participating retailers. Presumably for a good part of the summer.

Oreo is a sandwich cookie  consisting of two chocolate wafers with a sweet crème filling in between, and (as of 1974) are marketed as "Chocolate Sandwich Cookies" on the package they are held in. The version currently sold in the United States is made by the nabisco division.

Oreo has become the best selling cookie in the United States since its introduction in 1912. The origin of the name Oreo is unknown, but there are many theories, including derivations from the French word 'Or', meaning gold (as early packaging was gold), or the Greek word 'Oreo', meaning beautiful, nice or well done. Others believe that the cookie was named Oreo because it was short and easy to pronounce. According to a statement from Kim McMiller, an Associate Director of Consumer Relations, a two-stage process is used to make Oreo cookies.

The base cake dough is formed into the familiar round cookies by a rotary mold at the entrance of a 300-foot-long oven. Much of current Oreo production is done at the Kraft/Nabisco factory in Richmond, Virginia. Oreo cookies for the Asian markets are manufactured in Indonesia, India and China. Oreo cookies for Europe are made in Spain and in Ukrain.  for consumers in several CIS countries. Oreo cookies sold in Australia are manufactured in Indonesia (previously China) or Spain, depending on flavor.
