The Sing-Off finale didn't exactly reach fortissimo, but it helped NBC win the night with its 2.7 rating among 18-to-49-year-olds.
The two-hour show averaged 8 million-plus viewers, but was down 18 percent in the demo from the previous Monday. The premiere of Perfect Couples, which followed it at 10/9c, attracted just a 1.9 in 18-49.
Meantime, as 2010 draws to a close, MTV is crowing about a 16 percent year-over-year ratings increase among 12-to-34-year-olds — the network's largest annual increase since 1999. That's thanks to such shows as Jersey Shore — the network's most-watched series ever — and Teen Mom.
And MSNBC is touting how it beat CNN for the second straight year in prime-time among 25-to-54-year-olds — and for the first time in total viewers (873,000 vs. 641,000). Fox News Channel's ratings, however, continue to be more than double MSNBC's and CNN's combined.
