There were spies on ABC but it was truly show time on Fox and NBC last night. With its first live elimination show of Season 6, last night’s The Voice (2.7/9) rolled out a sizzling performance from mentor Shakira as well as cutting two contestants. Coming off its lowest Monday result ever and with the return of the Twitter instant save for a second season, the singing competition show was down 10% from last Tuesday. That’s a new low for the show in terms of regular episodes. Still, The Voice was the top-rated and most watched show of the night with 10.95 million watching. While NBC likely doesn’t want those standings to change, it might see a change in The Voice’s 18-49 rating later in the day when the final numbers come in – the show has commonly seen an adjustment upward from the preliminaries. With its 9:01 PM Voice spillover start, freshman About A Boy (1.9/6) saw a 6% bop up from last week in preliminary ratings. Fellow newbie Growing Up Fisher (1.5/4) was even with last week’s low. Getting a 1.8/5 among the 18-49s, NBC was No. 1 last night with an all-encore CBS coming in tops in total viewers with 9.41 million watching. CBS’ NCIS repeat was the second-most-watched show of Tuesday’s primetime after The Voice with an audience of 10.42 million.
