Adam Silver replaces David Stern as NBA commissioner

Adam Silver has become the NBA's fifth commissioner. The NBA posted a picture on its Twitter account Saturday of Silver holding a basketball and shaking hands with outgoing commissioner David Stern.

''It's official: Adam Silver succeeds David Stern as NBA Commissioner'' the caption read.

Stern retired after exactly 30 years in charge, making him the NBA's longest-serving and most successful commissioner.

Silver joined the NBA as his assistant in 1992 and has been the deputy commissioner since 2006.
