Infomercials

An infomercial is a long-form television advertisement, typically 28 to 30 minutes long, that presents a product or service in a program-like format resembling a talk show, news program, or product demonstration rather than a conventional commercial. The form emerged as a distinct advertising category in the United States in 1984, when federal restrictions on how much advertising time television stations could carry were relaxed, and it became a fixture of late-night television by the end of that decade.¹

Key fact	Detail
Typical length	Full-length commercial segments of about 28 to 30 minutes combining product news and entertainment; the CRTC defines the form as a program longer than 12 minutes²^•³
Regulatory turning point	US federal limits on advertising time were relaxed in 1984 under the Reagan administration; although Vitamix aired a 30-minute blender demonstration in 1949, Herbalife's 60-minute dietary supplement advertisement aired in 1984, and thus was not the first television infomercial.¹^•¹³
Information content	A study of over 200 infomercials found an average of 5.82 information cues per program, more than any other advertising media, with product availability, components, and performance the most frequent cues⁴
Share of airtime	Infomercials account for nearly one-fourth of the programming time on most cable stations²
Direct response	Most orders generated by an infomercial occur within about 24 hours of airing, making sales effects easy to measure compared with traditional commercials²
US disclosure rule	FTC cases have required a clear on-screen statement that the program is a paid advertisement, shown at the beginning and again before ordering information⁵

Origins and growth

The form's precursors were the two-to-four-minute commercials of the entrepreneur Ron Popeil, first aired in the 1950s, and the long-form advertisements for the Ginsu Knife in the 1970s.¹ Program-length advertising on American television had existed in scattered forms since the 1950s and became more prevalent after 1984.⁶ Once the 1984 deregulation removed the time restrictions, the first full-length infomercial aired that same year: a sixty-minute advertisement for dietary supplements produced by Herbalife.¹

Rapid adoption. Broadcast and cable stations facing budget constraints, increased competition, and growing demand for twenty-four-hour programming adopted infomercials as an alternative to conventional programming because they boosted advertising revenue.¹ By the end of the 1980s infomercials had become a fixture of late-night television, profitable for both broadcasters and marketers.¹ The form also spread internationally: New Zealand viewers first saw infomercials in December 1993, and the format flourished there through 1997, a period in which the wider economy was contracting.⁶

Format and content

Infomercials came to follow a standard format: thirty-minute broadcasts designed to mimic news programs, talk shows, or public service announcements, usually airing late at night and at other times when airtime was inexpensive. They showcase a specific product or group of products, often demonstrated dramatically, with a paid "audience" participating in demonstrations or staged question-and-answer sessions. Featured products have included tools and appliances, cleaning supplies, and programs on personal fitness, wealth creation, or dieting, often promoted as "miracle" products. Some advertised items are sold in retail stores, but many can be purchased only through contact information, usually a toll-free telephone number, given during the broadcast.¹

Information density. Using the Resnik and Stern coding method, a 1996 study of more than 200 infomercials on major broadcast and cable networks found that infomercials averaged 5.82 information cues, far more than any other advertising media, and that the amount and type of information varied by program format and product category.⁴ A content analysis of deceptive infomercials prosecuted by the FTC found that these programs tended to cite independent research rather than company-sponsored research to support claims, and that the nine cases studied represented about 17 percent of all deceptive infomercials the FTC had prosecuted.⁷ A coding of 318 infomercials and 861 commercials broadcast in Israel in the late 1990s found that functionalism appeared more than three times as often in infomercials as in commercials, while altruism was more than three times more frequent in commercials; despite their greater length, infomercials addressed a narrower range of values, repeatedly covering price, basic characteristics, and obvious uses.⁸

Effectiveness

Design elements. A survey of 878 New Zealand consumers who had bought products in response to viewing an infomercial found that infomercial advertising was more effective when it employed expert comments, testimonials, product demonstrations, target market models, celebrity endorsers, product comparisons, and bonus offers. Age and the type of product purchased also affected how consumers viewed the programs.¹²

Format length. Two experiments using a real infomercial for a rock music album compared a 1-minute ad, a 15-minute infomercial, and a 30-minute infomercial. Both infomercial lengths produced greater impact on recall, attitudinal, and purchase-intent measures than the ad, and few significant differences separated the infomercial from direct experience with the product, suggesting infomercials work more like product trial than like ordinary advertising. Within the infomercial conditions, the 15-minute format was most effective for attitudinal and direct-response measures, indicating that the popular 30-minute format may not be optimal.⁹

Persuasion mechanism. Research on why infomercials persuade despite exaggerated claims proposes a two-factor model drawn from "illusion of truth" studies, separating explicit information learning from implicit truth judgments. In experiments, the infomercial format itself was the most persuasive condition at both explicit and implicit levels, while the same information presented as text was judged most believable but persuaded least. Discounting cues presented before the infomercial lowered its persuasive impact, but a cue presented afterward, although it reduced explicit believability, left the implicit acceptance of the claims intact.¹⁰

Regulation

In the United States, the Federal Trade Commission applies its general truth-in-advertising rules to infomercials: advertisers must have proof for all express and implied claims that reasonable consumers would take from the ad, and health or safety claims generally require competent and reliable scientific evidence.⁵ Infomercial-specific policies add that the program must not deceptively mimic the format of news reports, talk shows, or other independent programming, and FTC cases have required the disclosure "THE PROGRAM YOU ARE WATCHING IS A PAID ADVERTISEMENT FOR [NAME OF PRODUCT]" at the beginning of the infomercial and before ordering information is given. Endorsements by consumers, celebrities, or experts fall under the FTC's Guides Concerning the Use of Testimonials and Endorsements, and infomercial producers can be liable for deceptive claims alongside the marketer.⁵

Under the FTC's 900 Number Rule, in infomercials lasting 15 minutes or longer, disclosures for pay-per-call services must be made at least three times, near the beginning, middle, and end of the commercial, and the cost must be stated each time the 900 number is announced.¹¹ In Canada, the CRTC requires broadcasters to clearly inform viewers that infomercials are paid commercial advertising.³

Cultural impact

Because infomercial formats mimicked news and public affairs programming and aired in time slots previously reserved for such programming, many viewers mistook advertisers' claims for objective information from authoritative sources.¹ The proliferation of advertising presented as news in the 1980s coincided with greater emphasis on entertainment and sensationalism in television news, making distinctions between fact and fiction harder for viewers to maintain, and the form both influenced and reflected the decade's consumer culture.¹ For marketers, the format suits technologically complicated products that need detailed explanation, and its rapid, measurable sales response aligns with demands for marketing accountability.²
