Antitrust refers to the body of laws and regulations that are designed to promote competition in the marketplace and prevent anti-competitive practices. These laws aim to protect consumers from monopolies, price-fixing, and other activities that may harm competition and limit choices for consumers. Antitrust laws are enforced by government agencies, such as the Federal Trade Commission (FTC) and the Department of Justice, through investigations and legal actions against companies that violate these laws. The goal of antitrust laws is to ensure fair competition, lower prices, and better quality products and services for consumers.
