Antitrust policy is a policy effected to make companies act in a competitive manner by breaking up companies that are monopolies, prohibiting mergers that would increase market power, and finding and fining companies that collude to establish higher prices while Industrial regulation is government regulation of firms’ prices (or “rates”) within selected industries. Therefore antitrust policy is designed to promote competitions while industrial regulations are designed to control price or rates of commodity of a product.
The government varies in choosing industrial regulation or antitrust policy due to different interpretation of the law. For instance different administration will hold different view on the effectiveness of the anti trust laws. Administrations holding a laissez-faire philosophy about monopoly have sometimes ignored them or have reduced the budgets of the enforcement agencies. Therefore the effectiveness of the anti trust law will solely depend with how the courts interprets them.

DuPont cellophane case of 1956 the Court defined
the market very broadly. While Du Pont controlled 100 percent of the cellophane market its market included all “flexible packaging materials”—waxed paper, aluminum foil, which were not a monopoly of DuPont. As Standard Oil was divided into several firm to compete Microsoft was cautioned against it behavior to stop in engaging in a set of specific anticompetitive business practices.
