Steve Ballmer

Steven "Steve" Ballmer is the chief executive officer of Microsoft, having held that post since January 2000. As of 2012, his personal wealth is estimated at $15.7 billion, ranking number 19 on the Forbes 400.

Steve Ballmer joined Microsoft on June 11, 1980, and became Microsoft's 30th employee, the first business manager hired by Gates.

Ballmer was initially offered a salary of $50,000 as well as a percentage of ownership of the company. When Microsoft was incorporated in 1981, Ballmer owned 8 percent of the company. During the subsequent 20 years, Ballmer headed several Microsoft divisions, including operations, operating systems development, and sales and support. In January 2000, he was officially named Chief Executive Officer. As CEO, Ballmer handled company finances; however Gates still retained control of the "technological vision". He served as President of Microsoft from July 1998 to February 2001, having previously served as Executive Vice President, Sales and Support since February 1992. Ballmer led Microsoft's development of the .NET Framework.

In 2003, Ballmer sold 8.3% of his shareholdings, leaving him with a 4% stake in the company.

There was tension surrounding the 2000 transition of authority from Bill Gates to Ballmer. Things became so bitter that, on one occasion, Gates stormed out of a meeting in a huff after a shouting match in which Ballmer jumped to the defense of several colleagues, according to an individual present at the time. After the exchange, Ballmer seemed remorseful. “Once Gates leaves, I’m not going to need him for anything. That's the principle," Ballmer said. "Use him, yes, need him, no."

In 2005, Mark Lucovsky alleged in a sworn statement to a Washington state court that Ballmer became enraged upon hearing that Lucovsky was about to leave Microsoft for Google, picked up his chair, and threw it across his office. Referring to Google CEO Eric Schmidt, Ballmer vowed to "kill Google" in an expletive-laden tirade then resumed trying to persuade Lucovsky to stay at Microsoft. Ballmer has described characterizations of the incident as a "gross exaggeration of what actually took place".

During a Web 2.0 Summit in San Francisco(2011) he said: "You don’t need to be a computer scientist to use a Windows Phone and you do to use an Android phone…It is hard for me to be excited about the Android phones."

On March 6, 2008, Seattle's Mayor announced that a local ownership group involving Ballmer made a "game changing" commitment to invest $150 million in cash toward a $300 million renovation of Key Arena and were ready to purchase the Seattle SuperSonics in order to keep them in the City of Seattle. However, this initiative failed, and the Sonics have since relocated to Oklahoma City, now performing as Oklahoma City Thunder.
