Pepsi is a carbonated soft drink with a cola flavor, manufactured by PepsiCo which serves as its flagship product. In 2023, Pepsi was the second most valuable soft drink brand worldwide behind Coca-Cola; the two share a long-standing rivalry in what has been called the "cola wars".
Pepsi, originally created in 1893 by Caleb Bradham and named "Brad's Drink," was first sold in his drugstore in New Bern, North Carolina. Renamed Pepsi-Cola in 1898 due to its supposed digestive benefits, its name was shortened to Pepsi in 1961. The beverage's formula initially included sugar and vanilla but not pepsin, despite speculation on the origin of its name. Early on, Pepsi struggled with financial stability, going bankrupt in 1923 but was subsequently purchased and revived by Charles Guth, who reformulated the syrup. Pepsi gained popularity with the introduction of a 12-ounce bottle during the Great Depression and clever marketing strategies like the "Nickel, Nickel" jingle, doubling sales by emphasizing its value.
