Pepsi was originally created and developed in 1893 by Caleb Bradham in the United States. It was known as Pepsi-Cola in 1898 before being shortened to Pepsi in 1961. The name "Pepsi" was derived from the word dyspepsia (indigestion) and "Cola" referring to the cola flavor. Some have also suggested that "Pepsi" may have been a reference to the drink aiding digestion like the digestive enzyme pepsin, but pepsin itself was never used as an ingredient in Pepsi-Cola.
Despite various rumors and claims, such as "Pay Every Penny to Save Israel," there is no credible evidence linking the name "Pepsi" to such an acronym. The company has never formally defined the origin of the name, and there is no historical or official connection between Pepsi and the suggested acronyms.
In addition, there are various humorous and nonsensical expansions of the acronym "PEPSI" listed on abbreviations.com, but these are not related to the actual origin or meaning of the brand name.
