Fortune 100 Fastest-Growing Companies
Even amid the worst economic slump since the Great Depression, some companies just keep growing.

And not only in the U.S. For the first time, Fortune opened its 100 Fastest-Growing Companies list to businesses around the world (if they trade on a U.S. exchange and file quarterly reports)—a change that landed Canada's Research in Motion in the No. 1 spot and two Chinese companies in the top 10.

To compile the list, Fortune ranked companies based on three years of revenue and profit growth and total return, using data provided by Zacks Investment Research.
