The Sherman Antitrust Act has been used by the federal government to break up many large monopolies, including Standard Oil and AT&T. It has also been used to prevent mergers and acquisitions that would have resulted in too much concentration of power in one company.
The Sherman Antitrust Act has been successful in promoting competition and protecting consumers from the harmful effects of monopolies. However, some critics argue that the act is too broad and that it can be used to prevent legitimate business practices.
Here are some of the specific results of the Sherman Antitrust Act:
- The breakup of Standard Oil. Standard Oil was one of the most powerful monopolies in American history. It controlled over 90% of the oil refining business in the United States. In 1911, the Supreme Court ruled that Standard Oil was a monopoly and ordered it to be broken up into 34 smaller companies.
- The breakup of AT&T. AT&T was the largest telecommunications company in the United States. It controlled over 90% of the long-distance telephone market. In 1982, the Justice Department filed a lawsuit against AT&T, alleging that it was a monopoly. In 1984, AT&T agreed to a settlement that required it to break up into seven regional Bell operating companies.
- The prevention of mergers and acquisitions. The Sherman Antitrust Act has been used to prevent many mergers and acquisitions that would have resulted in too much concentration of power in one company. For example, in 1998, the Justice Department blocked the merger of Staples and Office Depot because it would have created a monopoly in the office supply market.
