The National Bohemian began hocking their beer in half-dozens in the 1940s, and now that Pabst Blue Ribbon owns the company, they take credit for the invention of the six-pack. Ballantine, too, claimed to have invented the six-pack in 1938, and Florida's own Jax Brewing Co. is said to have come up with the idea of selling multiple beers in burlap sacks before plastic rings were invented.
