Oreo has gone through a few name changes over the years, initially going by “Oreo Biscuits,” then “Oreo Sandwich,” “Oreo Crème Sandwich,” and “Oreo Chocolate Sandwich Cookie” in the 1970s. Oddly, the core name remains a total mystery. The origin of the word “Oreo” might be from the French word for gold (or) because the packaging in the beginning was gold, but no one knows for sure.
The first new Oreo flavor to be added to the cookie's line-up was lemon cream. They've since released dozens of variations.

The first flavor they added to the brand was a lemon-filled Oreo, but it was soon discontinued, according to Biscuit People. It wasn't until the 2000s when the company began releasing numerous limited edition and holiday-themed flavors every year.
