Ratings: NBC's Sound of Music Live! Does Something Very Good; Glee and Grey's at Lows

Ratings Sound of Music LiveHow do you solve a problem like a boorish, overly snarky Twitter feed? By hushing the haters with huge numbers.

Facing off against 100-percent original broadcast competition throughout its entire three-hour run, NBC’s The Sound of Music Live! on Thursday night put 18.6 million total bums in the seats (as they say on Broadway), while scoring a 4.6 demo rating (per finals).

That marks NBC’s largest non-sports Thursday audience since May 2004 (when Frasier’s finale night averaged 22.6 mil) and its best non-sports Thursday demo number since the April 2009 ER finale (5.2).

Save for its opening face-off against the always formidable Big Bang Theory — which won the night with an adjusted-up 4.8 rating — SOML at least doubled the numbers of 9 of the night’s 11 other broadcast programs.

TVLine readers meanwhile gave the production an average grade of “B-.”

NBC notes that, unsurprisingly, the top local market among the metered market households came from Oklahoma City, in female lead Carrie Underwood’s home state.

In other words, the countdown until NBC greenlights Taylor Swift’s Evita Live! starts now.
