In two to three sentences, describe how antitrust laws encourage competition

A monopoly is a company or business that dominates a particular market to such an extent that there is no viable competition to that company; Antitrust laws prevent monopolies by breaking up or limiting monopolies' size, allowing other companies to enter a market.
