Reuters’ Alastair Sharp has published a story saying that some investors are wondering whether it’s time for a change at the top of BlackBerry maker Research in Motion, which is led by Mike Lazaridis (who founded the company in 1984) and Jim Balsillie (who’s been co-CEO since 1992). Sharp’s piece follows a flurry of debate last week about the future of Steve Ballmer, Microsoft’s president and CEO, who’s been with the company since 1980 and has been CEO since 2000.
I’m not making any predictions about what’s going to happen at either company–except to note that lack of change is usually a more likely outcome than change in these situations, at least in the short term. But the stories got me thinking about the durability of many of the top executives in tech companies. I decided to graph out the management of a few major corporations.
