Step-by-step explanation:
The term used to describe when a brand name becomes synonymous with a product category is called genericide. Band-Aid has done a great job at building brand recognition to the extent that many consumers in the United States use the term "Band-Aid" to refer to all types of bandages and wound care products, regardless of the brand.
This phenomenon of brand names becoming generic terms is not unique to Band-Aid. Other examples include Kleenex for tissues, Xerox for photocopies for internet searches. When a brand achieves this level of recognition and becomes synonymous with the product category, it is a strong indication of successful brand building.
