Atleast part of the reason is a dwindling supply:
In tech circles, the C-suite at a publicly traded company is no longer the be-all and end-all. Just look at the troubles Yahoo! (YHOO) and Hewlett-Packard (HPQ) have recently had finding new leaders. HP canned former SAP (SAP) Chief Executive Officer Léo Apotheker after just 11 months—then faced a barrage of criticism for replacing him with HP director and former EBay (EBAY) CEO Meg Whitman without bothering to look beyond its own boardroom.
Industry consolidation has created a small number of very large technology companies such as HP, Cisco (CSCO), and Microsoft (MSFT). They’ve stumbled in recent years as disruptive developments like the mobile revolution and the dash to the cloud shake the entire sector. As the job of leading these companies gets tougher, there are fewer talented leaders with the skills—and inclination—to do it. Rather than wait for high-profile CEOs such as Cisco’s John Chambers, Microsoft’s Steve Ballmer, and Research In Motion’s (RIMM) Mike Lazaridis and Jim Balsillie to step down, many potential replacements have decamped for more exciting, and potentially more lucrative, gigs at startups or as investors. “This is the first time in tech history that you have this many companies with CEOs approaching 60 that don’t have any obvious successors,” says John Thompson, vice-chairman of recruiting firm Heidrick & Struggles (HSII).
