Bill Veghte, Ray Ozzie, Bob Muglia and Steven Sinofsky. B. Kevin Turner, Microsoft's Chief Operating Officer (COO), was considered by some to be a de facto number two to Ballmer, with Turner having a strong grasp of business and operations but lacking technological vision. On February 4, 2014, Satya Nadella succeeded Ballmer as CEO. Public image Although as a child he was so shy that he would hyperventilate before Hebrew school, Ballmer is known for his energetic and exuberant personality, which is meant to motivate employees and partners, shouting so much that he needed surgery on his vocal cords. Ballmer's excited stage appearances at Microsoft events are widely circulated on the Internet as viral videos. One of his earliest known viral videos was a parody video, produced for Microsoft employees in 1986, promoting Windows 1.0 in the style of a Crazy Eddie commercial. Ballmer and Brian Valentine repeated this in a spoof promotion of Windows XP later on. A widely circulated video was his entrance on stage at Microsoft's 25th anniversary event in September 2000, where Ballmer jumped across the stage and shouted "I love this company!" Another well-known viral video was one captured at a Windows 2000 developers' conference, featuring a perspiring Ballmer chanting the word "developers". Relationship with Bill Gates Ballmer was Gates' best man at his wedding to Melinda French, and the two men described their relationship as a marriage. They were so close for years that another Microsoft executive described it as a mind meld. Combative debates—a part of Microsoft's corporate culture—that many observers believed were personal arguments occurred within the relationship; while Gates was glad in 2000 that Ballmer was willing to become CEO so he could focus on technology, the Wall Street Journal reported that there was tension surrounding the transition of authority. Things became so bitter that, on one occasion, Gates stormed out of a meeting 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", the person said. 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 October 2014, a few months after Ballmer left his post at Microsoft, a Vanity Fair profile stated that Ballmer and Gates no longer talk to each other due to animosity over Ballmer's resignation.
