[{"role": "system", "content": "Pepsi is a carbonated soft drink produced and manufactured by PepsiCo. Originally created and developed in 1893 by Caleb Bradham and introduced as Brad's Drink, it was renamed as Pepsi-Cola on August 28, 1898, and then as Pepsi in 1961. The drink Pepsi was first introduced as \"Brad's Drink\" in New Bern, North Carolina, United States, in 1893 by Caleb Bradham, who made it at his drugstore where the drink was sold. It was renamed Pepsi-Cola in 1898 after the root of the word \"dyspepsia\" and the kola nuts used in the recipe. The original recipe also included sugar and vanilla. Bradham sought to create a fountain drink that was appealing and would aid in digestion and boost energy. In 1903, Bradham moved the bottling of Pepsi-Cola from his drugstore to a rented warehouse. That year, Bradham sold 7,968 gallons of syrup. The next year, Pepsi was sold in six-ounce bottles, and sales increased to 19,848 gallons. In 1909, automobile race pioneer Barney Oldfield was the first celebrity to endorse Pepsi-Cola, describing it as \"A bully drink...refreshing, invigorating, a fine bracer before a race.\" The advertising theme \"Delicious and Healthful\" was then used over the next two decades. In 1926, Pepsi received its first logo redesign since the original design of 1905.\n"}, {"role": "assistant", "content": "Drink much soda?
