#1) Will Ferrell, Chris Henchy and Adam McKay: The trio’s venture FunnyorDie.com has funny videos featuring celebrities, comedians and you.

In addition, Fifty founded the G-Unit Clothing company, has dabbled in movies and consumer products, and has used his Web sites, 50cent.com and thisis50.com, to push the promotion of 50 Cent events and memorabilia arguably more than any urban rap artist to date.
