Document 3: Pepsi-Cola Made with Real Sugar: The Pepsi - Cola Made with Real Sugar, formerly called Throwback, is a brand of soft drink sold by PepsiCo in the United States and in sweet stores in South Australia for its flagship Pepsi and Mountain Dew brands. The drinks, called Pepsi Throwback and Mountain Dew Throwback, are named as such because they are flavored with cane sugar and beet sugar instead of high fructose corn syrup, which soft drink companies used to replace sugar (in their North American products) in the 1980s. In addition, these drinks use retro packaging. As of June 2014, Pepsi Throwback has been replaced in one area of the United States by ``Pepsi - Cola Made with Real Sugar '', a new product formulation, also made without high fructose corn syrup.

In 1962, Dr Pepper released a diet (etic) version of its soft drink, although it sold slowly due to the misconception that it was meant solely for diabetic consumption.
