All about Pepsi-Cola

Pepsi was first made in New Bern, North Carolina, in the United States in the early 1890s by pharmacist Caleb Bradham. In 1902, "Brad's Drink" was changed to "Pepsi-Cola" and later trademarked on June 16, 1903. There are several theories on the origin of the word "pepsi".
Pepsi gained popularity following the introduction in 1936 of a 12-ounce bottle. Initially priced at 10 cents, sales were slow, but when the price was slashed to five cents, sales increased substantially. With a radio advertising campaign featuring the jingle "Pepsi cola hits the spot / Twelve full ounces, that's a lot / Twice as much for a nickel, too / Pepsi-Cola is the drink for you," Pepsi encouraged price-watching consumers to switch, obliquely referring to the Coca-Cola standard of six ounces a bottle for the price of five cents (a nickel), instead of the 12 ounces Pepsi sold at the same price. Coming at a time of economic crisis, the campaign succeeded in boosting Pepsi's status. In 1936 alone 500,000,000 bottles of Pepsi were consumed. From 1936 to 1938, Pepsi-Cola's profits doubled.
Pepsi's success under Guth came while the Loft Candy business was faltering. Since he had initially used Loft's finances and facilities to establish the new Pepsi success, the near-bankrupt Loft Company sued Guth for possession of the Pepsi-Cola company. A long legal battle, Guth v. Loft, then ensued, with the case reaching the Delaware Supreme Court and ultimately ending in a loss for Guth
