The societal and economic dangers of monopolies are clear. To combat the effects of these large corporations, the government has tried, through both legislation and court cases, to regulate monopolistic businesses.
Indeed, the government never tried to stifle a corporation simply because it was strong. Instead, regulation exists to preserve competition and the freedom for smaller companies to enter the market. If one company controls the market share, smaller groups will never be able to flourish. For example, the dominance of Microsoft in recent years has raised the question of whether its practices are monopolistic. Because the corporation controls the majority of the market in nearly all of its markets, there is an overwhelming social pressure for regulation.
