Extra gum was launched by Wrigley's in 1984 as their first sugar-free product and quickly became one of the top gum brands in the United States. Wrigley's was founded in 1891 by William Wrigley Jr., originally selling products like soap and baking powder before beginning to package gum with baking powder cans in 1892. Wrigley's uses humor and comedy in their advertising, like a wanted poster for their Extra gum depicting it as police stopping "crimes against teeth" committed by food, and a Bazooka gum ad showing a character blowing large bubbles to break his fall.
