Affect theory on the nose
Affect theory on the nose
The “Have a Coke and a Smile” campaign, launched by Coca-Cola and McCann Erickson in the late 1970s, didn’t tiptoe around its message. It went straight for the heart. By literally telling consumers to smile, the campaign linked Coke directly to happiness in the boldest and most literal way possible. No, metaphor or nuance. It was more on the nose than including puppies in your advertisement. It was affect theory in action, spelled out in a simple slogan. In an era where Pepsi was pushing taste tests, Coca-Cola doubled down on emotional impact. They realized that taste is not necessarily the driving factor in purchasing decisions between the two soft drinks; Coke wanted to be the one that made you feel good. And they didn’t leave that up to chance, they told you to feel good, with a Coke in hand.
The most iconic example of this campaign was the 1979 “Hey Kid, Catch!” ad starring NFL legend “Mean” Joe Greene (my personal favorite commercial of all time, even before studying affect theory). A young fan offers the grumpy, 6'4", 275-pound behemoth-of-a-man a Coke. After downing it in one gulp, Greene smiles and tosses the boy his game jersey. The transformation from tough guy to softie is simple but powerful. The moment Greene smiles, the message lands: Coke brings joy. Penny Hawkey, a copywriter on the campaign, later explained that what made the ad work wasn’t the celebrity or the drink, but it the emotional core: “Storytelling is what made it special,” she said in an interview. “You got this really gruff guy who softens. That’s the moment. That’s the smile.”
Another team member, producer Phil Messina, emphasized the simplicity behind the campaign's emotional punch: “We wanted to connect to basic human feelings, no matter where you were watching it,” he said. The team succeeded. The ad won awards, generated massive public response, and even inspired international versions featuring local sports heroes. It remains one of the most recognized and beloved commercials in advertising history.
“Have a Coke and a Smile” was affect-based advertising at its most on the nose, yet most effective. It didn’t just make people happy. It told them how to feel, and that direction, backed by a warm story and a universal emotion, became one of the most powerful brand messages ever delivered. By blending emotional storytelling with a literal call to joy, Coca-Cola managed to brand not just a beverage, but a feeling.
