RIM (now BlackBerry)
RIM invented the "smart" phone with its BlackBerry line and for years it was coined "CrackBerry." But the past three years have been rough on the company as it got pummeled by the popularity of Android and the iPhone. Revenue and market share have taken a hard hit, and many have written off the Canadian company. But BlackBerry is on the hunt for a big bounce-back this year with a new OS (BlackBerry 10) and new phones (the Z10 and Q10).
