1. It all started back in 1891.

When William Wrigley Jr. moved to Chicago, he started selling soap and baking soda and decided one day to throw in a free pack of chewing gum with customers' orders.

2. Juicy Fruit is the original label.

Just a few months before Wrigley's Spearmint was introduced in 1893, Juicy Fruit was released. To this day, over 100 years later, it remains the number one fruit brand in the U.S. and the most popular choice among kids. Doublemint didn't come along until 1914.

3. Doublemint is double everything.

When it debuted, Doublemint was advertised as having "double value," "double strength peppermint flavor," and being "double wrapped."

4. Wrigley invented a new marketing technique.

Way back in 1915, founder William Wrigley Jr. made a bold move by doing something totally unprecedented for that time: He sent free samples to every address listed in the U.S. phone books. It was the first-ever direct-marketing campaign at home.

5. There are three Wrigley factories in the U.S.

Outside of Chicago, there are production facilities in Santa Cruz, CA that opened in 1954 and Gainesville, GA that opened in 1971. Plus, there are even more abroad in Australia and Great Britain.

6. The first Doublemint Twins appeared in 1960.

Joan and Jane Boyd were the first pair to become Wrigley Double mint Twins, starring in commercials for four years straight. Since then, various other twins—including Tia and Tamera Mowry—have starred in the brand's commercials.

7. It also owns Life Savers.

In 2005, Wrigley purchased the Life Savers mint company—which was created in 1912 as a summer candy that could take the heat better than chocolate—plus the Altoids, Creme Savers, and Sugus brands.

8. Big Red arrived in 1976.

It came onto the scene with the slogan "kiss a little longer." It's only available in the United States, Germany, and Canada.

9. Wrigley gum is dentist-approved.

Orbit, Extra, and Eclipse sugargree gums were the first in the U.S. to receive the American Dental Association's Seal of Acceptance.

10. There's a story behind the Hubba Bubba name.

It comes from the phrase "Hubba Hubba" which was used by soldiers during World War II to express approval.

11. Extra Sugar-Free Gum was created in 1984.

Following the '80s wave of low-cal, sugar-free gums on the market, Extra came around and quickly became consumers' go-to. Winterfresh and its "icy cool" flavor followed in 1994.
