More good news for NBC:* Even its repeat of The Voice performed strong. Wednesday night’s two-hour encore of Tuesday’s Voice premiere delivered a rating that was actually the network’s highest number in that time period in a month.

The Voice picked up another 6 million viewers — half its debut audience — and had a 2.1 rating in the adult demo. The show would have posted a 2.3 rating, because that’s what it had in three of its half-hours, but the program’s first half hour — and this is where it gets interesting — overlapped with American Idol. That part was only a 1.7. While Idol gained during each of its half hours, including the part that overlapped with The Voice.

Now, since The Voice was a repeat, we can’t read too much into this, but it’s probably fair to say these two definitely have some audience overlap. Next month, these two will go head-to-head and we’ll hopefully see some ratings fireworks.

Meanwhile, Idol (21.7 million viewers, 6.9 preliminary adults 18-49 rating) was roughly on par, while Breaking In (7.6 million, 2.6) gained slightly to rank as the night’s highest-rated comedy.

CBS’ Survivor (10.9 million, 3.0) hit a series low, followed by repeats. ABC’s comedy block had Better with You (4.8 million, 1.5) and Cougar Town (5.6 million, 2.1) down to season lows, but look at this: Happy Endings (5.2 million, 2.1) jumped 17 percent to match its lead in — a good sign.

* man that felt weird to type!
