Diet Pepsi was originally created in the U.S. under the name Patio in 1963. Following a positive reception attributed to the shifting dietary habits and preferences among the Baby Boom Generation at the time, the drink was re-branded as Diet Pepsi the following year. It became the first diet cola to be distributed on a national scale in the United States.[1] Distribution was extended to the U.K. in 1983,[2] where it is also referred to as Diet Pepsi.[3] Distribution has since expanded to other countries around the world; though an alternate name is used in certain countries. In Italy,[4] Czech Republic,[5]Poland[6] Argentina,[7] Spain[8] Greece,[9] Turkey,[10] Ukraine,[11] and Brasil,[12] the beverage is known as Pepsi Light.
Diet Pepsi competed primarily with another diet cola named Tab in the 1960s and 1970s; however the Coca-Cola Company introduced Diet Coca Cola in 1982 and this product has since been the principal competing product to Diet Pepsi. As of 2010, Diet Pepsi represented a 5.3 percent share of all carbonated soft drink sales in the United States, and was ranked as the #7 soft drink brand da volume. In the same year, Diet Coca Cola was recorded as having a 9.9 percent market share.[13]
