In 1871, a tobacco company called Pearl Tobacco did something that had never been done in advertising: it put a woman’s naked torso on its packaging. The packaging was a box of cigarettes. The strategy worked — people talked about it, bought it, and other brands started copying it. More than 150 years later, the same approach powers Victoria’s Secret catalogs, Axe body spray commercials, and Carl’s Jr. ads featuring Kate Upton eating a burger in slow motion. The logic seems unassailable: sex gets attention, and attention is the first step to a sale. What could possibly go wrong?
🧠 The Meta-Analysis No One Wanted to Hear
In 2013, a team led by John Wirtz at the University of Illinois published a paper in the International Journal of Advertising that should have been a wake-up call for the entire industry. They performed a meta-analysis of 78 peer-reviewed studies on the effects of sexual advertising campaigns — decades of data, hundreds of experiments, thousands of participants.
The finding was devastatingly clear: sexual content makes an ad more memorable, but that memorability does not transfer to the brand or product being advertised. People remember “that sexy ad with the actress eating a burger.” They do not remember “oh right, that was Carl’s Jr.”
Wirtz put it plainly: “We found that people remember ads with sexual appeals more than those without, but that effect doesn’t extend to the brands or products that are featured in the ads.”
The same attention that makes a sexy ad stand out gets absorbed by the sexual content itself. Something called the vampire effect — the creative element sucks all the blood from the message, leaving nothing for the brand.
🤔 The Gender Gap No One Talks About
Wirtz’s meta-analysis turned up another finding that was even less convenient for the industry: females consistently disliked sexual ads, while males liked them. The gender gap was stark enough that Wirtz called it “the strongest finding” of the entire analysis, adding that the researchers “were surprised at how negative female attitudes were toward these ads.”
This creates a structural problem for any brand whose customer base is not 100% young men. If sex in advertising actively alienates half your potential audience, the attention you gain from the other half comes at a steep cost. Tom Reichert, former head of the University of Georgia’s Department of Advertising, noted that sex only works within narrow bounds: “Sex is not as effective when selling high-risk, informational products such as banking services, appliances and utility trucks.” In other words — if what you’re selling requires trust, expertise, or considered thought, sexual imagery actively undermines your message.
🔗 The Product Decides, Not the Ad
Reichert’s 30-year study of magazine ads (3,232 full-page ads across 1983, 1993, and 2003 in Cosmopolitan, Esquire, Playboy, Newsweek, Time, and Redbook) revealed a telling pattern: sex in advertising is concentrated in a small set of product categories. Health and hygiene (38%), beauty (36%), drugs and medicine (29%), clothing (27%), travel (23%), entertainment (21%) — these are products where sex has a natural connection. Body wash ads show skin because body wash involves skin. Perfume ads hint at intimacy because perfume is marketed as a romantic tool.
The industries that don’t use sex — banking, enterprise software, professional services, nonprofit organizations — don’t use it because it would undermine their core message. A charity using sexual imagery to raise awareness for child poverty would be a catastrophe. A SaaS company using it to sell CRM software would look desperate. The medium is not just the message — the medium is the product.
For a high-trust, high-consideration product like a personal AI companion or a personalized reading service, the implication is clear: sexual appeals are not just ineffective — they’re counterproductive. The emotional register that builds trust and intimacy over time is fundamentally different from the one that grabs attention for three seconds.
🎲 The GoDaddy Reversal
Perhaps the most instructive case study is GoDaddy. For years, the domain registrar ran ads featuring scantily clad women and sexually suggestive humor. The strategy made the brand famous. It also made it a punchline. In 2012, facing pressure from its own customers and the broader business community, GoDaddy pulled the entire campaign. New CEO Blake Irving declared that the company was done being “the bad boy of the internet.” Revenue went up.
Sex sells attention. It has never reliably sold anything else.
