Ep.4: Halitosis, the monster of bad breath


Get ready for a journey back in time as we unearth a mind-blowing advertising campaign. What happens when a brand decides to play on our deepest fears to sell its product? Marketing genius or a desperate move? Let's find out in this episode.


Fear sells

In the roaring 20s, a mouthwash brand called Listerine set out to conquer the market with a bold strategy: turn bad breath into public enemy number one. How did they do it? By creating a made-up medical term, "halitosis," to describe bad breath and associating it with devastating social consequences like rejection, loneliness, and even romantic failure.


Listerine painted a terrifying picture in which bad breath was an invisible monster lurking, ruining the lives of its victims without them even realizing it. The solution, of course, was Listerine mouthwash, the only one capable of defeating this fearsome enemy and guaranteeing a full and happy social life.


Listerine's campaign was a resounding success. Mouthwash sales skyrocketed, and the brand became a market leader. People rushed to stores to buy Listerine, terrified of the possibility of having bad breath and suffering the terrible consequences the brand had described.


However, Listerine's success came at a price. The campaign created a new social anxiety around bad breath, making it a much bigger problem than it really was. In addition, it set a precedent for the use of fear tactics in advertising, which have since been used to sell all sorts of products, from insurance to toothpaste.


Does the end justify the means?

Listerine's campaign is a perfect example of how fear can be a powerful motivator, but also how it can be used to manipulate consumers. The brand exploited the fear of social rejection to create an artificial need for its product, generating unnecessary anxiety in many people.


While the campaign was effective from a commercial standpoint, it raises serious ethical questions about the responsibility of brands when communicating their messages. Is it right to play on people's fears to sell a product? What ethical boundaries should brands respect in their pursuit of commercial success?


The question for the AI

How would you evaluate the effectiveness of a marketing campaign that creates a fictitious medical term ("halitosis") to describe bad breath, associating it with negative social consequences and presenting its product as the only solution to avoid rejection and failure?

The AI's response: The campaign, while undoubtedly effective in terms of sales and brand recognition, raises serious ethical concerns from a modern marketing perspective.


Negative Aspects:

  • Anxiety creation: The campaign exaggerates the social consequences of bad breath, creating unnecessary anxiety in consumers and exploiting their insecurities.

  • Deceptive tactics: The invention of a fictitious medical term and the presentation of the product as the only possible solution are manipulative tactics that can be considered misleading.

  • Negative social impact: The campaign can contribute to stigmatizing bad breath, making it a more serious social problem than it really is.


Ethical Alternatives:

Instead of resorting to fear and manipulation, you could opt for a more educational and empowering campaign. You could inform about the causes of bad breath, offering practical advice to prevent it and presenting the product as a useful tool, but not as the only solution.


In addition, you could highlight the benefits of mouthwash in terms of oral health, such as the prevention of cavities and gum disease, rather than focusing solely on the social consequences of bad breath.

A Predictive Revenue Marketing proposal

This example is presented for educational purposes to illustrate how Listerine could utilize Predictive Revenue Marketing. The goal is to demonstrate how this strategy can go beyond vanity metrics and focus on generating revenue sustainably.

  • Objective: Increase Listerine's sales revenue by identifying and targeting customer segments with the highest probability of purchase and lifetime value.

  • Strategy Used:

    • Predictive analysis: Utilize past purchase data, web behavior, or demographic data to create predictive models that identify customers most likely to purchase Listerine and those with the highest potential long-term value. Segment customers based on their specific oral health needs and preferences (e.g., concern about bad breath, tooth sensitivity, whitening).

    • Personalized campaigns: Develop personalized marketing campaigns for each customer segment, using messages and offers relevant to their specific needs and concerns. Utilize programmatic advertising platforms to deliver these campaigns in real time to customers on the most opportune channels and times. Example: Show Listerine ads with a focus on bad breath to a customer who has searched for information on this topic.

    • Predictive lead scoring: Utilize predictive models to score leads based on their probability of conversion and potential value. Prioritize sales and marketing efforts on leads with the highest probability of generating revenue.

    • Price optimization: Offer personalized discounts and promotions to customers based on their purchase history and likelihood of response.

  • Measuring Success:

    • Sales Revenue: Increase in revenue generated by Listerine sales.

    • Return on Investment (ROI): Measurement of the return on investment in marketing campaigns.

    • Conversion Rate: Percentage of leads that convert into customers.

    • Customer Lifetime Value (CLTV): Total value that a customer is expected to generate throughout their relationship with the brand.

  • Important note: When implementing these campaigns, it is crucial that companies address ethical concerns related to the use of customer data, ensuring transparency, informed consent, and privacy protection. Additionally, steps must be taken to avoid biases in algorithms and ensure that marketing campaigns are fair and equitable for all consumers.
