LeBron leads ABC to big numbers

ABC's Christmas Day NBA broadcast of the Miami Heat routing the Los Angeles Lakers gave the network its biggest audience on the holiday since 2004.

This year's matchup, showcasing LeBron James in his much-anticipated first visit since joining the Heat to play Kobe Bryant and the Lakers in Los Angeles, had a 6.4 fast national rating, compared with 4.4 when James' Cavaliers played the Lakers last Dec. 25. Earlier on Saturday, a Boston-Orlando clash had a 4.6, 39 percent better than last year's matchup between the same two teams. 

Together, ABC's two Christmas Day games were up 45% in households compared to a year ago, and ESPN's three games were up 20%.
