Monopoly - Breaking Up Monopolies

Breaking Up Monopolies

When monopolies are not ended by the open market, sometimes a government will either regulate the monopoly, convert it into a publicly owned monopoly environment, or forcibly fragment it (see Antitrust law and trust busting). Public utilities, often being naturally efficient with only one operator and therefore less susceptible to efficient breakup, are often strongly regulated or publicly owned. American Telephone & Telegraph (AT&T) and Standard Oil are debatable examples of the breakup of a private monopoly by government: When AT&T, a monopoly previously protected by force of law, was broken up into various components in 1984, MCI, Sprint, and other companies were able to compete effectively in the long distance phone market.
