Category killer is a term used in marketing and strategic management to describe a product, service, brand, or company that has such a distinct sustainable competitive advantage that competing firms find it almost impossible to operate profitably in that industry (or in the same local area). The existence of a category killer eliminates almost all market entities, whether real or virtual. Many existing firms leave the industry, thereby increasing the industry's concentration ratio.
