Coca-Cola Tested New Coke on 200,000 People. Then

Coca-Cola tested a new formula on nearly 200,000 consumers. The taste results looked strong. Seventy-nine days after the launch, the company announced the return of the original formula as Coca-Cola Classic. So what did the research miss? This evidence-led business investigation reconstructs the competitive pressure behind New Coke, what the taste tests actually measured, how consumers responded to permanent replacement, why historical accounts use both 79 and 80 days, and why the popular publicity-stunt theory remains unverified. The deeper lesson is not that data is useless. It is that research must test the decision customers will actually face—not only one attribute inside a controlled comparison. Margin & Motive Bureau follows the evidence behind famous corporate decisions, hidden business models, costly mistakes, and unexpected consequences. Every business has a motive. Every decision has a cost. Primary and supporting sources include The Coca-Cola Company history archive, contemporaneous reporting from TIME, The Washington Post and the Los Angeles Times, the INSEAD New Coke case description, and analysis published by the American Marketing Association.
