Description:

Wrigleys Gum all started with William Wrigley Jr. Once he had moved to Chicago, he decided to start selling soap and baking soda. One day he decided to throw in a free pack of chewing gum with customers' orders - Wrigleys Gum was born.

During 1915 William Wrigley sent free samples to every address listed in the U.S. phone books. It was the first-ever direct-marketing campaign of its kind.
