In the 20th century, chewing gum made William Wrigley Jr. one of the richest men in America. Wrigley (0) started out as a soap salesman in his hometown of Philadelphia.
After moving to Chicago in 1891, he offered store owners free cans of baking powder with every order. When the baking powder proved a bigger hit than the soap, Wrigley sold that
and added in free packs of chewing gum as a promotion.
In 1893, he launched two new gum brands: Juicy Fruit and Wrigley’s Spearmint. The chewing gum field
crowded with competitors.
Because of that, Wrigley decided he'd make his products
by spending heavily on advertising, sending free samples of chewing gum to millions of American adults, and to children on their second birthday.
The competition also
a role in the development of bubble gum. Frank Fleer had been making chewing gum since 1885 and spent years working on a product that could be blown into bubbles. Finally, he developed the first commercial chewing gum, called Dubble Bubble.
The idea of a three-course dinner chewing gum - tasting like tomato soup, roast beef and blueberry pie - has
to become reality. Gum is sold in a variety of shapes and flavours and is still around today.
