The NBA Development League, founded in 2001, is the NBA's official minor league and features 16 teams with direct affiliations to NBA teams for the 2009-10 season.

The NBA D-League is an engaging and innovative sports property that embodies the dedication and passion for basketball shared by its promising and talented players. We pride ourselves on our deep roots to the NBA, the bonds that we forge with our local communities, and the accessibility and excitement we provide our fans and partners.

Two expansion teams will begin play in Portland, Maine and Springfield, MA for the 2009-10 season. Sixty former NBA Development League players were on 2008-09 NBA start-of-season rosters, and the league continues to develop current NBA coaches and referees.
