Step 1 : Introduction to the question "Which soft drink was originally called "Brad's 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 later labeled Pepsi Cola, named after the digestive enzyme pepsin and kola nuts used in the recipe. Bradham sought to create a fountain drink that was delicious and would aid in digestion and boost energy. The original trademark application for Pepsi-Cola was filed on September 23, 1902 with registration approved on June 16, 1903.
