List year: 2009
When RIM released the Blackberry in 2003, there was nothing like it on the market. Businesses and IT professionals loved the smartphone so much that it was, at first, able to hold its market share even after the introduction of the iPhone in 2007. RIM was the top company on Fortune's 2009 fastest-growing list. But the company overestimated its staying power, and banked on its great security settings to keep corporate customers buying its phones.
The company wasn't prepared for the current trend of employees bringing in their own devices made by consumer-focused companies like Google and Apple to work. Now, RIMM is working with JPMorgan and RBC Capital to "review its strategic options." In other words, anything, including a sale, could be on the table for the Canadian tech company.
