Coke came first. It was first made in 1886. Pepsi was first made in 1898.
The Pepsi Generation was the theme of an advertising campaign for Pepsi-Cola, a U.S. brand of soft drink, that launched in 1963. It was the brainchild of Alan Pottasch, a Pepsico advertising executive. It invited consumers to "Come Alive! You're the Pepsi Generation!"
Earlier campaigns for Pepsi-Cola had emphasized price competition. Twelve ounce Pepsi bottles gave you twice as much soft drink as six ounce standard Coca-Cola bottles, and Coca-Cola was by far the leading brand of soft drink. Pepsi formerly ran a campaign that featured the jingle:
Food and drink
Diet Pepsi is a no-calorie carbonated cola soft drink produced by PepsiCo, introduced in 1964 as a variant of Pepsi-Cola with no sugar. First test marketed in 1963 under the name Patio Diet Cola, it was re-branded as Diet Pepsi the following year, becoming the first diet cola to be distributed on a national scale in the United States. In the 1960s and 1970s its competition consisted of Tab, produced by The Coca-Cola Company, and Diet Rite soda, produced by Royal Crown. Diet Coke was a later entrant to the diet cola market; though shortly after entering production in 1982 it became the primary competing diet cola to Diet Pepsi.
While the U.S. represents the largest single market for Diet Pepsi, it was launched in the U.K. in 1983 and has since become available on a global scale. The beverage composition, flavor variations and packaging varies based on the country of production. In some countries - primarily in Eastern Europe - the product is labeled and sold under the name Pepsi Light. In the UK it is called Pepsi Diet.
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry.
Soft matter is a subfield of condensed matter comprising a variety of physical states that are easily deformed by thermal stresses or thermal fluctuations. They include liquids, colloids, polymers, foams, gels, granular materials, and a number of biological materials. These materials share an important common feature in that predominant physical behaviors occur at an energy scale comparable with room temperature thermal energy. At these temperatures, quantum aspects are generally unimportant. Pierre-Gilles de Gennes, who has been called the "founding father of soft matter," received the Nobel Prize in physics in 1991 for discovering that the order parameter from simple thermodynamic systems can be applied to the more complex cases found in soft matter, in particular, to the behaviors of liquid crystals and polymers.
