The William Wrigley Jr. Company is a company headquartered in the Wrigley Building in Chicago, Illinois. The company was founded on April 1, 1891, originally selling products such as soap and baking powder. In 1892, William Wrigley Jr., the company’s founder, began packaging chewing gum with each can of baking powder. The chewing gum eventually became more popular than the baking powder itself and Wrigley’s reoriented the company to produce the popular chewing gum.
The company currently sells its products in more than 180 countries and maintains 140 factories in various countries, including the United States, Mexico, Australia, the United Kingdom, Canada, Spain, New Zealand, the Philippines, Czech Republic, Germany, South Africa, Argentina, Tanzania, Tunisia, Somalia, North Korea (the only US enterprise there) France, Kenya, Taiwan, China, India, Poland, and Russia.
