BlackBerry’s head of BBM leaves company

BlackBerry(s bbry) might not be doing too well, but BlackBerry Messenger (BBM) has seen a recent uptick in popularity, thanks to new Android(s goog) and iOS(s aapl) apps. It comes as a surprise, then, that the executive VP in charge of BBM, Andrew Brocking, has left the company. BlackBerry confirmed Brocking’s departure on Monday to BGR. CNET is reporting that it was Brocking’s decision to leave the company, and John Sims, head of global solution, will now manage the BBM group. BlackBerry CEO John Chen had previously mentioned the company’s hopes for turning BBM into a revenue stream, though it is unclear how it plans to do so and if Brocking’s departure will have an effect.
