In 1908, Sunshine Biscuits introduced a crème-filled sandwich cookie known as the Hydrox, which received a decent reception. Shortly after, Nabisco launched their own version of the treat, the Oreo Biscuit. Initially, the Oreo had lackluster sales, but it quickly gained popularity, leading to Hydrox being mistakenly perceived as a knock-off brand and eventually fading into obscurity. In 1921, Nabisco rebranded their product as the Oreo Sandwich, and later introduced variations such as the Oreo Creme Sandwich in 1948 and the Oreo Chocolate Sandwich Cookie in 1974, which is the current full name (although commonly referred to simply as Oreo due to its widespread usage since the 1960s). The origin of the name remains unofficial, with theories suggesting it may be derived from the oreodaphne genus of the laurel family, as many Nabisco products are named after plants, or simply designed for brevity and ease of pronunciation.
