<Tr> <Td> "</Td> <Td> To hear some tell it, April 23, 1985, was a day that will live in marketing infamy...spawning consumer angst the likes of which no business has ever seen . </Td> <Td>" </Td> </Tr> <Tr> <Td_colspan="3">--The Coca - Cola Company, on the New Coke announcement </Td> </Tr> <P> New Coke was introduced on April 23, 1985 . Production of the original formulation ended later that week . In many areas, New Coke was initially introduced in "old" Coke packaging; bottlers used up remaining cans, cartons and labels before new packaging was widely available . Old cans containing New Coke were identified by their gold colored tops, while glass and plastic bottles had red caps instead of silver and white, respectively . </P> <P> The press conference at New York City's Lincoln Center to introduce the new formula did not go well . Reporters had already been fed questions by Pepsi, which was worried that New Coke would erase its gains . Goizueta, Coca - Cola's CEO, described the new flavor as "bolder", "rounder", and "more harmonious", and defended the change by saying that the drink's secret formula was not sacrosanct and inviolable . As far back as 1935, Coca - Cola sought kosher certification from an Atlanta rabbi and made two changes to the formula so the drink could be considered kosher (as well as halal and vegetarian). Goizueta also refused to admit that taste tests had led the change, calling it "one of the easiest decisions we've ever made .") A reporter asked whether Diet Coke would also be reformulated "assuming (New Coke) is a success," to which Goizueta curtly replied, "No . And I didn't assume that this is a success . This is a success ." </P>

When did they change the coca cola recipe
