Fast National ratings for Tuesday, June 18, 2013.
 
A Game 6 thriller in the NBA Finals easily lifted ABC to a Tuesday win among young viewers, but NBC  still eked out an overall win for the night with a boost from the season finale for "The Voice."
 
With the exciting climax of the basketball game taking place outside of primetime on the East Coast and early in primetime on the left side of the country, you can expect plenty of shifting when the Final numbers come in, though ABC is suggesting this could be the fourth highest-rated NBA game in network history.
 
As for the finale of "The Voice," NBC wanted to emphasize that it was the show's most watched finale overall and that it outdrew May's finale for "American Idol," while FOX wanted to counter that among young viewers, "The Voice" was down by 12 percent from its fall/winter finale.
 
For the night, ABC averaged a 5.4 rating among adults 18-49, beating NBC's 3.8 rating in the key demographic. There was a big gap to third place FOX's 1.4 rating and to the 0.9 key demo rating for CBS, while The CW drew a 0.3 key demo rating.
 
Overall, though, NBC averaged an 8.6 rating/14 share and 14.01 million viewers, compared to the 8.2/13 and 13.7 million viewers for ABC for the night. CBS was third with 6.43 million viewers and a 4.3/7 for the night, well ahead of the 3.85 million viewers and a 2.4/4 for FOX. The CW averaged 652,000 viewers and a 0.4/1 for the night.
