It is also one of the favorite cookies for people to dunk into their milk. So if you’re looking for a sweet reason to enjoy one of these cookies, then you might want to celebrate this day on March 6^th.

The History of National Oreo Day

In 1912, the National Biscuit Company (now known as Nabisco) introduced the Oreo cookie to the world. However, at the time, it wasn’t called a cookie but was instead referred to as the Oreo Biscuit. On March 6th, 1912, the company filed for a trademark on this cookie and was granted one by March 14, 1912. It is considered by many to be a copy of the Hydrox Cookie, which was developed some four years earlier by the Sunshine Company.

The first Oreos sold for 25 cents a pound and were sold in cans with a clear top. Nine years after the Oreo Biscuit was first sold, the National Biscuit Company decided to change the name to the Oreo Sandwich. During the 1920s, the Oreo underwent a couple of design changes, which included a new design in 1924 and the release of a now short-lived lemon-filled Oreo. After World War II, the Oreo Sandwich underwent another name change, becoming the Oreo Crème Sandwich in 1948.

Over the years, a variety of different Oreos were developed and sold to the public. These included the Double Stuf Oreo in 1974, the Football Oreo in 1976, Big Stuf Oreo in 1987, Oreo Minis in 1991, Mega Stuf Oreos in 2013, and Oreo Thins in 2015. A number of limited-edition cookies were also manufactured and sold to the public. These included Birthday Cake Oreos, Lemon Twist Oreos, Fruit Punch Oreos, Cinnamon Bun Oreos, Key Lime Pie, Gingerbread Oreos, and Pumpkin Spice Oreos.

National Oreo Day is celebrated on March 6^th because that is when the term “Oreo” was first used on the trademark forms in 1912. Once people realized this little fact, the day was quickly turned into a holiday.
