The former Microsoft CEO is now an NBA owner.
In a statement Tuesday, the NBA said the league's "Board of Governors previously approved the sale and Ballmer is now the Clippers Governor."
"I am humbled and honored to be the new owner of the Los Angeles Clippers," Ballmer said in a statement released by the team.
"Clipper fans are so amazing. They have remained fiercely loyal to our franchise through some extraordinary times. I will be hard core in giving the team, our great coach, staff and players the support they need to do their best work on the court. And we will do whatever necessary to provide our fans and their families with the best game-night experience in the NBA."
