Mars knows chocolate sales are nothing to snicker at. The company makes global brands M&M's, Snickers, and the Mars bar. Other confections include 3 Musketeers, Dove, Milky Way, Skittles, and Twix. Its products portfolio also boasts Seeds of Change organic food, the Klix and Flavia beverage systems, Combos and Kudos snacks, Uncle Ben's rice, and pet food made under the Pedigree, Sheba, and Whiskas labels. Mars owns the world's largest chewing gum maker, Wm. Wrigley Jr. Company, as well. The Mars family -- including siblings and chairman John Franklyn Mars, VP Jacqueline Badger Mars, and former CEO Forrest Mars Jr. -- owns the highly secretive company, making the family one of the wealthiest in the US.
