If most companies within one industry are using the same unfair or deceptive practices, how can the Federal Trade Commission protect consumers?

When most companies within one industry are using the same unfair or deceptive practices, bringing actions against all of the companies would be costly and time-consuming. An alternative method of addressing the practices is through trade regulation rules. If the Federal Trade Commission finds that deception is pervasive in an industry, the Federal Trade Commission can recommend rule making. An administrative rule has the effect of law. Furthermore, the Federal Trade Commission can bring legal action against those who violate Federal Trade Commission rules.
