Why did Coca-Cola bring back its original formula after the New Coke backlash?

The Coca-Cola Company reintroduced its original formula as "Coca-Cola Classic" on July 11, 1985, after only 77 to 79 days, in response to an overwhelming public backlash against New Coke.12

While the company had conducted extensive taste tests suggesting consumers preferred the sweeter, reformulated drink, the launch was met with widespread outrage. Consumers viewed the replacement of the original beverage as a "national disaster," leading to protests, the hoarding of original supplies, and thousands of complaints from customers and bottlers alike.12

Ultimately, the company recognized that it had underestimated the deep emotional and cultural connection consumers held toward the original brand. As noted by the CEO of Pepsi-Cola USA, the experience taught the company that it could not simply alter the taste or imagery of its flagship product without abandoning its heritage. By bringing back the original formula, the company sought to restore its relationship with its loyal customer base.12
