Microsoft has stepped into a new and uncertain era with the announcement that CEO Steve Ballmer will retire within 12 months, triggering a search for a successor to take over the software behemoth.
The announcement on Friday surprised analysts and investors and sent shares surging, reflecting belief that the company will benefit from new leadership as it tries to innovate and chase the market for smartphones and tablets.
"There is never a perfect time for this type of transition, but now is the right time," Ballmer said in a statement.
