Facebook will stream a live sports event for the first time when the social media website simulcasts a Cleveland Cavaliers pre-season training camp practice Thursday featuring NBA superstar LeBron James. The NBA Real Training Camp show will air on NBA TV as well as the league's website starting at 11 a.m. (1500 GMT). The program features interviews with players, coaches and team executives as well as playmaking from the workout of the Cavaliers, who lost to the Golden State Warriors in last June's NBA Finals.
