Which soft drink was first introduced as "Brad's Drink"?

Pepsi is a carbonated soft drink 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.

During the Great Depression, Pepsi-Cola gained popularity following the introduction in 1934 of a 12-ounce bottle. Prior to that, Pepsi and Coca-Cola sold their drinks in 6.5-ounce servings for about $0.05 a bottle. With a radio advertising campaign featuring the popular jingle "Nickel, Nickel," Pepsi encouraged price-conscious consumers to double the volume their nickels could purchase.
