Diet Coke
Diet Coke does not use a modified form of the Coca-Cola recipe, but instead an entirely different formula. The controversial New Coke, introduced in 1985, used a version of the Diet Coke recipe that contained high fructose corn syrup and had a slightly different balance of ingredients. In 2004, Coca-Cola introduced Coca-Cola C2, which it claims tastes much closer to Coca-Cola but contains half the carbohydrates. In 2005, the company introduced Coca-Cola Zero (replaced by "Coca-Cola Zero Sugar" in 2017), a sugar-free variation of regular Coca-Cola.

Goizueta also made a visit to his mentor and predecessor as the company's chief executive, the ailing Robert W. Woodruff, who had built Coke into an international brand following World War II. He claimed he had secured Woodruff's blessing for the reformulation, but even many of Goizueta's closest friends within the company doubt that Woodruff understood Goizueta's intentions.
