Caleb Davis Bradham was born in Chinquapin, North Carolina, on May 27, 1867. After graduating from the University of North Carolina, Bradham attended the University of Maryland School of Medicine in hopes of becoming a doctor. While attending school he worked part-time as a pharmacy apprentice at a local drug store.
Unfortunately, a family crisis forced Bradham to drop his pursuit in medicine and return home to North Carolina. Upon returning, he taught school for a short period of time before opening a drug store on the corner of Middle and Pollock Streets in downtown New Bern. Bradham's Drug Store would later become the very place Pepsi-Cola was invented. In 1893, “Brad’s Drink,” made from a mix of sugar, water, caramel, lemon oil, nutmeg, and other natural additives, became an overnight sensation. Despite its name and hearsay, pepsin was never an ingredient of Pepsi-Cola.
On August 28, 1898, Bradham renamed his drink “Pepsi-Cola." He believed the drink was more than a refreshment but a “healthy” cola, aiding in digestion, getting its roots from the word dyspepsia, meaning indigestion.
In late 1902, the Pepsi-Cola Company was formed due to the rising popularity and demand for the Pepsi-Cola Syrup with none other than Caleb Bradham as the first president. The business began to grow, and on June 16, 1903, "Pepsi-Cola" became an official trademark. By 1904, the Pepsi-Cola Syrup sales reached almost 20,000 gallons. As demand for the drink continued to rise, Bradham decided it was time to offer Pepsi-Cola in bottles. At the peak of success, Bradham had authorized Pepsi-Cola franchises in over 24 states.
However, on May 31, 1923, Bradham and his Pepsi-Cola Company declared bankruptcy. The major factor for Bradham's business failure was the price of sugar immediately following World War I, when prices went up to 28 cents per pound (it was three cents per pound pre-war), and Bradham had purchased a large amount of sugar at that price but the price of sugar nosedived soon after he purchased it. The assets of his company were sold to the Craven Holding Company for $30,000. After declaring bankruptcy, Bradham returned to operating his drug store. He died in New Bern, Craven County, North Carolina.
In 1931 the company’s trademark and assets were picked up by Charles G. Guth (1876–1948), founder of the modern Pepsi-Cola. He established a new Pepsi-Cola Company, had a chemist formulate a better drink, set up new bottling operations, and began merchandising a hugely successful 12-ounce bottle for five cents. When in 1941 the Pepsi-Cola Company was merged into Loft, the name Loft, Inc., was changed to Pepsi-Cola Company.
In the early 21st century, PepsiCo focused on expanding its operations in other countries, notably Russia, which was its second-largest market. As of January 26, 2012, 22 of PepsiCo's brands generated retail sales of more than $1 billion, and the company's products were distributed across more than 200 countries, resulting in annual net revenues of $43.3 billion.
