Just consider the teenagers below. Whether aged 13 or 19, or somewhere in between, they're all busy running their own companies, creating their own apps, or starring in their own YouTube channels. Some even began their business before their teen years - two on this list got to work at age nine.

From creating million-dollar online retailers to launching product lines with Target and Whole Foods, see how these $4 teens are making money.
