Today marks the two-year anniversary of Mike Lazaridis and Jim Balsillie leaving BlackBerry. There was certainly plenty of news over the course of their tenure at BlackBerry, but there was arguably more that went down at BlackBerry in just the two short years after they left the company than all of the previous years combined. 

The two stepped down from their positions as co-CEO in January 2012 and Thorsten Heins took the wheel for what would be a bumpy road. During his time as CEO we saw the company rebranded from RIM to BlackBerry, new execs appointed, the addition of Frank Boulben as CMO (and of course Alicia Keys), the launch of BlackBerry 10 and BlackBerry's "strategic review" and the company nearly going private. Sadly things didn't go quite as planned under Thorsten Heins' watch and in November of last year he too stepped down from BlackBerry as John Chen was named the new BlackBerry CEO. 

Here's a look at the biggest stories to come from BlackBerry over the past two years:




John Chen is now a few months into his role at CEO of BlackBerry. He's already hard at work behind the scenes — changing up some of the executive team, sorting out a partnership with Foxconn and going full-steam ahead with his new strategy for BlackBerry. So far, so good. The stock price is up on the news of the Pentagon activating 80,000 devices and it doesn't look like things are slowing down. Chen knows what he wants and will do whatever he needs to in order to execute his plan. 

We'll see how things pan out over the next few months, but looking back it's crazy to see just how much has gone down with BlackBerry since Mike and Jim stepped down.
