NEW YORK (AP) — More viewers are tuning into the NBA — and it's not just the fascination with the Miami Heat.

Television ratings for games on ESPN and TNT are up more than 30 percent so far this season.

Sure, the Heat are drawing big audiences after a summer of free agent intrigue concluded with LeBron James and Chris Bosh joining Dwyane Wade in Miami. Ratings for Heat games on ESPN have increased 69 percent from last season.

But take out the five matchups involving Miami, and the network's NBA coverage is still up 23 percent from a year ago.
