What Happened to New Coke? Why the Better Formula Disappeared in 1985

Through the 1970s and early 1980s, Coca-Cola watched a lead it had held since the Second World War drain away. After the war the company held roughly 60% of the American cola market. By 1983 that share was under 24%, and Coca-Cola's own corporate history concedes its lead over its chief competitor, in its flagship market and with its flagship product, had been slipping for 15 consecutive years. Pepsi was winning in supermarkets, where a shopper chooses freely, and what was left of Coke's lead sat in vending machines and fast-food fountains. The answer was Project Kansas, a secret programme run by marketing vice president Sergio Zyman and Coca-Cola USA president Brian Dyson, whose strategy paper compared the coming launch to the Allied invasion of Europe in 1944. Nearly 200,000 consumers were tested. The new formula beat the old one 55-45 blind, and 61-39 once the label was shown. On 23 April 1985 chairman Roberto Goizueta stood up at Lincoln Center and called it "the surest move ever made". Roger Enrico of Pepsi took a full page in The New York Times and gave his staff the day off. 79 days later, on 11 July 1985, president Donald Keough announced the original was coming back as Coca-Cola classic. In this video, we tell the story of New Coke - the reformulation that won every taste test it was ever given and still had to be withdrawn in 79 days. In this documentary: 1. The Quiet Swap: How Coca-Cola moved to high-fructose corn syrup from 1980, five years before anybody objected to the formula. 2. Project Kansas: Why a $4 million research programme compared itself to D-Day. 3. The Sip Test: How an instrument that tests one person alone measured taste perfectly and social influence not at all. 4. The Question Nobody Asked: Why secrecy made it impossible to ask a tester how they would feel if the original were withdrawn. 5. 79 Days: How the hotline went from 400 calls a day to 31,600 in 48 hours. 6. The Coup That Was Not: Why no national television advertising ran for Coca-Cola classic in August 1985. 7. What Survived: How the argument over cane sugar reached American shelves again in 2025. What remains is not the drink. It is the finding that a measurement taken one person at a time cannot predict what those people do in a room together, and that Coca-Cola's research was never wrong, only blind in exactly one direction.
