Fast National ratings for Sunday, June 7, 2015.

For the first time in NBA history, the Finals started with consecutive overtime games and the showdown between the Cavaliers and Warriors produced a second consecutive primetime domination for ABC on Sunday night.

ABC is estimating that this will be the highest-rated NBA Finals Game 2 ever on the network and posted 26 percent gains over last year's Game 2. These Fast National numbers, of course, reflect time period data and, as always, are extra imprecise when one of the competing teams has a fan homebase on the  West Coast.

Sunday night's other notable was CBS' broadcast of the 69th Tony Awards, which dipped from last year both overall and among young viewers, falling by 25 percent in the key demo. 

Also down on Sunday were NBC's "A.D. The Bible Continues," which hit a series low, and "American Odyssey."

Let's get to the numbers...

Among adults 18-49, ABC averaged a 5.3 rating for Sunday night, more than doubling the combined total for the competition in the key demographic. CBS was second with a 0.9 key demo rating, followed by NBC's 0.7 key demo rating and the 0.6 key demo rating for FOX for the night.

Overall, ABC averaged an estimated 13.865 million viewers and a 7.9 rating/14 share for Sunday primetime, still doubling up the 6.81 million viewers and 4.5/8 for CBS on the night. NBC was third with 4.06 million viewers and a 2.6/5, followed by FOX's 1.49 million viewers and a 0.9/2.
