Research In Motion on Tuesday named two new executives as the shake-up atop its organization continues. Recently-appointed chief executive officer Thorsten Heins said during his first day on the job that finding a new marketing boss and making drastic changes to the company’s marketing strategy were top priorities for the struggling smartphone maker. While the company’s marketing efforts have yet to pay off — though it does seem to be trying new things, at least — a new chief marketing officer has now been named. Frank Boulben, former executive vice president of strategy, marketing and sales for LightSquared, has been appointed CMO effective immediately, and joining him is new chief operating officer, Kristian Tear, who comes from Sony Mobile where he was the company’s executive vice president. “Kristian and Frank bring extensive knowledge of the rapidly changing wireless global market and will help RIM as we sharpen our focus on delivering long-term value to our stakeholders,” RIM CEO Thorsten Heins said in a statement. “Most importantly, both Kristian and Frank possess a keen understanding of the emerging trends in mobile communications and computing.”
