In the 1950s the nature of advertising changed, and new critiques of advertising and consumption emerged. Advertising volume expanded along with the booming economy, and, perhaps more crucially, advertisers employed the new medium of television to reach their audiences. By 1960 advertisers spent over $1.5 billion on television. The new medium’s fusion of sight, sound, and motion in living rooms forced an expansion of the concept of truth in advertising. In 1970, for example, the FTC took action against Campbell Soup for a commercial for vegetable soup in which the photographers had put clear marbles at the bottom of a bowl to make the soup’s ingredients rise to the top and appear more abundant. Campbell agreed in a consent order to discontinue the procedure.

These changes set the stage for a revival of consumerism and new efforts to control advertising during the 1960s. Consumerists had long complained that the FTC and other regulatory agencies shared a revolving door with regulated businesses. Although self-regulation and government control had recognized some of the new problems, the major challenge to policy makers was to find appropriate ways to curtail the fraudulent abuses in advertising. In response, the FTC began a program requiring advertisers to provide information substantiating the claims they made in their publicity. Failure to supply adequate evidence, in the judgment of commission staff, could bring about a charge of deception or unfairness. Indeed, the FTC articulated a principle stating that advertising claims that lacked a “reasonable basis” for belief were unfair practices.

The FTC, however, had not been given the legal instruments or the staff necessary to effectively administer and monitor advertising. Moreover, in many cases, the FTC relied heavily upon making deals with companies, in the form of consent orders, to halt misleading or false advertising. In 1971, consultation among advertisers, agency, and media interests bore fruit in the creation of a new self-regulatory system. The scheme designated the National Advertising Division (NAD) of the Council of Better Business Bureaus as an investigating body and created a National Advertising Review Board (NARB) to evaluate complaints about advertising.

The purpose or mission of NARB was to “sustain high standards of truth and accuracy in national advertising.” In reviewing advertisements, if a panel of NARB decides that an advertisement is misleading or deceptive, it will request that the advertiser modify or withdraw the advertisement. If the advertiser does not respond or comply with the request, the panel will issue a Notice of Intent, warning that the issue will be made known to the public and government. NARB therefore serves as a self-regulatory agency, monitoring the activities of companies and agencies alike.

In the late 20th century, advertising expanded rapidly. In 1973 in the United States, advertising expenditures amounted to $25 billion; by 1993 they had increased to over $110 billion. From the mid-1970s, however, pressure for deregulation partially stymied governmental and industry efforts to regulate advertising. On the other hand, U.S. consumers became impatient with misleading and deceptive advertising. In almost every piece of merchandise a consumer buys, he or she is influenced consciously or unconsciously, directly or indirectly, by advertising. Some scholars declared that all advertising is deceptive because it is designed to manipulate. The major part of informative advertising is a campaign of exaggeration, half-truths, intended ambiguities, direct lies, and general deceptions. In the early 21st century, in polls on the honesty and ethics of people in different professions, advertising and advertising practitioners ranked near the bottom.

In addition to the FTC under the FTC Act, private parties, such as consumers or competitors, can bring legal action regarding false advertising under the Lanham Act. To establish a violation under the Lanham Act, consumers and competitors must prove that the advertiser made false statements, that the false advertisements actually deceived or had the capacity to deceive, that the deception was material, that the falsely advertised product was sold in interstate commerce, and that the party bringing the lawsuit (the plaintiff) was injured as a result of the deception. The penalties for a Lanham Act violation include the plaintiff’s lost profits, the additional profits to the advertiser resulting from the deceptive advertisement, treble damages, and attorneys’ fees.

In addition to the FTC Act and the Lanham Act, which are federal statutes, most U.S. states also have laws proscribing false advertising. For example, several states enforce the Uniform Deceptive Trade Practices Act, under which a so-called deceptive trade practice includes activities such as palming off, misrepresentation, product disparagement, and bait-and-switch advertising. Palming off occurs when an advertiser creates the impression that its goods or services are those that are furnished by a competitor. This can occur, for example, when a person or group sets up a business that resembles another, such as a hamburger restaurant that resembles a McDonald’s restaurant. Misrepresentation occurs when an advertiser makes false or misleading claims about its goods or services, as under the FTC Act and the Lanham Act. Product disparagement occurs when an advertiser intentionally makes false or misleading negative remarks about competing goods or services, causing its competitor to lose sales. Bait-and-switch advertising occurs when the advertised goods or services are withdrawn from the market and substitute goods or services are instead offered for sale.

Most states have laws, usually in the form of consumer fraud or deceptive practices statutes, that regulate advertising. Under these laws, state or local officials can seek injunctions against unlawful advertisements and take legal action to bring restitution to consumers. Some laws provide for criminal penalties, such as fines and jail, but criminal proceedings for false advertising are rare unless fraud is involved. A competitor harmed by unlawful advertising, or faced with the likelihood of such harm, generally has the right to seek an injunction and possibly an award of money (damages) as well, although damages are often difficult to prove. Such cases usually are based on one of two legal theories: unfair competition or commercial disparagement.

Difficulty of proof and a trend of lenience toward advertising fraud cases can be found in many countries worldwide. For example, in Canada each year, thousands of allegedly false, misleading, or deceptive advertisements have been reported to the Department of Consumer and Corporate Affairs, but only a small number of the cases resulted in recommendations to the attorney general for criminal prosecution. Overall, there have been very few convictions against advertising fraud worldwide.
