Trivia: What soda was the first to be sold in a 2-liter bottle?
Correct Answer: Pepsi
So why is this answer correct? : In the late 1960s, while working for DuPont Corporation, inventor Nathaniel Wyeth began working on a new type of plastic bottle that wouldn’t expand when storing carbonated beverages. In 1970, the company filed a patent for the “biaxially oriented poly(ethylene terephthalate) bottle,” and that same year, Pepsi designed the first 2-liter soda bottle. The new big-bottle concept helped Pepsi battle its way onto supermarket shelves and into family homes that often ran out of Coke, which was served only in 6.5-ounce bottles. The new bottles were among the catalysts that launched the Cola Wars of the 1980s.
