The English word Brand of the brand comes from the ancient Norwegian word Brandr, which means "burning". People use this method to mark private property such as livestock that needs to be distinguished from others. In medieval Europe, craftsmen used this branding method to mark their handicrafts so that customers could identify the origin and producer of the product. This creates the original trademark, which provides a guarantee to consumers and legal protection to producers. In the early 16th century, producers who distilled whiskey put the whiskey into wooden barrels branded with the producer's name to prevent unscrupulous traders from stealing the goods. By 1835, Scottish distillers adopted the brand "Old Smuggler" to maintain a reputation for the quality of liquor brewed using special distillation procedures. In the "Oxford Dictionary", a brand is explained as "used to prove ownership, as a sign of quality or for other purposes", that is, to distinguish and prove quality. As time goes by, the business competition landscape and the retail industry continue to change, and the meaning of brands has become more and more abundant, and even a specialized research field-brand science has been formed.
