RIM ranked the fastest growing company

BlackBerry Curve

BlackBerry-maker Research in Motion (RIM) is the company to watch, according to a new ranking by Fortune Magazine.

The Canadian smartphone firm was ranked first in a list of the fastest growing firms around the world. Fortune cited the success of the BlackBerry Curve in the US, noting RIM had held off challengers like the Apple iPhone to keep a 74 per cent share of the business smartphone market.

And with smartphone sales outpacing other handsets, RIM's growth looks set to continue.
