Microsoft’s ebullient CEO Steve Ballmer has been included in TIME magazine’s 100 most influential people list.

The larger-than-life Microsoft man has become an increasingly influential figure at the Redmond company since Bill Gates announced that he will step down in June this year.

Chief warrior

But it is business acumen that has planted him firmly among in the esteemed company of TIME’s list.

"He is actually Microsoft's combative, take-no-prisoners chief warrior," says Guy Kawasaki – the former Apple evangelist who wrote the  TIME profile.
