Pepsi-Cola, most commonly called Pepsi, is a soft drink produced by PepsiCo which is sold worldwide in stores, restaurants and vending machines. The brand was trademarked on June 16, 1903, though the drink was first made on August 28, 1898, by pharmacist Caleb Bradham. Similar to Coca-Cola, its major rival, Pepsi was originally intended to cure stomach pains.
