| | In the 1980s a more laissez-faire approach was adopted, underpinned by economic theories from the Chicago school. These theories said that the only justification for antitrust intervention should be that a lack of competition harmed consumers, and not that a firm had become, in some ill-defined sense, too big. Some monopolistic activities previously targeted by antitrust authorities, such as predatory pricing and exclusive marketing agreements, were much less harmful to consumers than had been thought in the past. They also criticized the traditional method of identifying a monopoly, which was based on looking at what percentage of a market was served by the biggest firm or firms, using a measure known as the herfindahl-hirschman index. Instead, they argued that even a market dominated by one firm need not be a matter of antitrust concern, provided it was a contestable market. | | In the 1980s a more laissez-faire approach was adopted, underpinned by economic theories from the Chicago school.

| − | In the 1990s American antitrust policy became somewhat more interventionist. A high-profile lawsuit was launched against Microsoft in 1998. The giant software company was found guilty of anti-competitive behavior, which was said to slow the pace of innovation. However, fears that the firm would be broken up, signaling a far more interventionist American antitrust policy, proved misplaced. The firm was not severely punished. | + | ===Microsoft=== |
