New Coke: Marketing Blunder or Master Plan?

In 1985, Coca-Cola replaced its flagship drink with a sweeter formula, then brought the original back 79 days later after a public outcry. Sales rose afterward, and some suspected the whole thing was a deliberate stunt. Company president Donald Keough denied it: 'The truth is we're not that dumb and we're not that smart.'

The Story

According to History.com, Coca-Cola found in secret taste tests that a sweeter version of its drink beat both Pepsi and the original Coke. On 23 April 1985, chairman and CEO Roberto Goizueta introduced the new formula at Lincoln Center in New York, calling it 'smoother, rounder, yet bolder.'

Loyal customers hated it. History.com says that within weeks the company was getting 5,000 angry phone calls a day, and 8,000 a day by June. Seventy-nine days after the launch, on 11 July 1985, executives announced that the original formula would return as 'Coca-Cola Classic.' The New York Times says the return led to a jump in overall sales.

'The truth is we are not that dumb and we are not that smart.'

The turnaround was so fast and so profitable that some suspected a plan. One theory said the company had changed the formula on purpose to remind people how much they loved the original. Another said it was cover for switching to cheaper corn syrup, but History.com notes that the recipe's sweeteners had already changed several times, including to corn syrup.

Coca-Cola denied it was a stunt. Company president Donald Keough said at the time: 'Some cynics say we planned the whole thing,' adding: 'The truth is we are not that dumb and we are not that smart.' No evidence of a plan has emerged, and the evidence of a genuine backlash is strong.
