Pepsi is a carbonated soft drink that is produced and manufactured by PepsiCo. Created and developed in 1893 - by Caleb Bradham - and introduced as Brad's Drink, it was renamed as Pepsi-Cola on August 28, 1898, then to Pepsi in 1961, and in select areas of North America, "Pepsi-Cola Made with Real Sugar" as of 2014. Bradham sought to create a fountain drink that was appealing and would aid in digestion and boost energy.
Coca-Cola is a carbonated soft drink sold in stores, restaurants, and vending machines throughout the world. It is produced by The Coca-Cola Company of Atlanta, Georgia, and is often referred to simply as Coke. Originally intended as a patent medicine when it was invented in the late 19th century by John Pemberton, Coca-Cola was bought out by businessman Asa Griggs Candler, whose marketing tactics led Coke to its dominance of the world soft-drink market throughout the 20th century.
