NEW YORK (AP) -- The NBA is adding its Twitter handle to its official game ball for next season. The league announced the change on Thursday. The handle (at)NBA will be added to the left of the league's logo, making it the first game ball to have it in any of the four major pro sports in North America. The NBA's Twitter account has 10.7 million followers, by far the most when compared to the NFL, MLB and NHL. Unlike a few years back when the league tried to introduce a new synthetic leather game ball, the Spalding ball's composition will not change. The league quickly abandoned the synthetic ball.
