Adam Silver begins reign as NBA commissioner

Adam Silver has officially taken over from David Stern as commissioner of the NBA.

The league's fourth commissioner has retired after a 30-year spell at the helm.

In a thank you email to the media, Stern said: "It is a source of great satisfaction to me that the NBA will now be led by commissioner Adam Silver, for whom I have tremendous admiration, respect and expectations as he and his experienced and dedicated team take the NBA to successes that were unimaginable even a short while ago."

Silver has been Stern's deputy since 2006, having joined the league as the commissioner's assistant in 1992.
