Video: NBA commissioner David Stern announces he will retire on Feb. 1, 2014.

David Stern will step down as commissioner of the NBA, effective Feb. 1, 2014.

Stern, 70, is the longest-tenured active commissioner in pro sports, running the NBA since Feb. 1,1984. He began working for the league as outside counsel in 1966.

“I don’t know what else to say other than to recite what i told the owners in executive session,” Stern said in a press conference. “It’s been a great run, it will continue for another 15 months. The league is in, I think, terrific condition.”

Deputy commissioner Adam Silver — most visible as the man who announces the second round of the NBA Draft — was unanimously approved as Stern’s successor by the NBA Board of Governors, the New York Times’ Howard Beck reported. Silver has worked for Stern for 20 years and, Stern said, “I could not be happier sitting here knowing that I will be succeeded by Adam.”

Stern said he knew his target date for retirement six months ago and that he was confident that Silver, who had a visible role alongside Stern during last year’s player lockout, was the best choice to succeed him. “What an honor to be in this position,” Silver said. “I’m honored, thrilled and will do my absolute best to grow this league.”

Stern’s tenure will have lasted exactly 30 years and will end one day before Super Bowl XLVIII in MetLife Stadium.
