lost profit(Lost sales, also referred to as lost revenue, income or profit, is a term used in the context of Internet piracy to refer to sales that did not occur because potential customers have chosen not to buy a product but to obtain it from an illegal source for a lower cost or for no cost. Figures for lost sales usually assume that consumers who use pirated content would always choose to purchase the product at the market rate, if the illegal sources were not available.
