Ratings: The Sing-Off Slips to a Finale Low, Hollywood Game Night Returns Steady

Ratings Sing-Off Season 4 FinaleThe Sing-Offs Season 4 finale was watched by 5.2 million total people and scored a 1.3 rating on Christmas Eve Eve, down sharply week-to-week (7.3 mil/2.0) and off 13 and 19 percent from its previous, circa-Nov. 2011 closer, thus hitting a series low for a finale.

Leading out of that, a holiday edition of Hollywood Game Night — in which Rachel Bilson rocked the bonus round like a boss — drew 3.5 mil and a 1.0, up 25 percent in audience and flat in the demo versus its Aug. 30 Season 1 finale. (Season 2 kicks off Monday, Jan. 20.)

Elsewhere and pending NFL-related deflation, ABC’s Great Christmas Light Fight closed its freshman run with 5.3 mil and a 1.4, up 33 and 40 percent week-to-week and on par with its season premiere. (With any luck, all those decorations will be down by Easter.)

Opening ABC’s night, Shrek the Halls (4.7 mil/1.2) was up 42 and 20 percent versus 2012, while A Chipmunk Christmas (4.6 mil/1.2) more than doubled its year-ago numbers. Ohhh-kay!
