Work It

This is how much of a drag the premiere of the poorly reviewed Work It was: the show put up numbers worse than those that got its predecessor, Man Up!. canceled.

The new series — which has already been criticized by GLAAD and deemed "an instant early candidate for Worst Show of 2012" — posted a 2.0 rating among 18-to-49-year-olds. That's 17 percent below the opening demo of the time slot's previous occupant, which managed to attract 7.7 million viewers for its debut, according to Nielsen overnights. (The series sank to 4.8 million viewers by its final outing.)

Meanwhile, The Biggest Loser scored a demo rating 30 percent lower than its January debut a year ago: 2.3 — an all-time low for its springtime run.

CBS scored its best Tuesday night since Premiere Week as NCIS broke the 20 million mark for the second time this season and its spin-off NCIS: Los Angeles pulled in its biggest audience of the season. Unforgettable also returned to easily win the final prime-time hour.

Finally, for those keeping score at home, CBS has taken the lead over Fox in the industry-prized demo after 15 weeks of the 2011-12 TV season (through Sunday, Jan. 1) -- 3.2 vs. 3.1. ABC and NBC are tied with 2.5. And The CW is last with 0.8. In viewership, CBS remains way in front of the pack, averaging 12.11 million viewers. Next comes ABC (8.70 million), Fox (8.57 million), NBC (7.37 million) and The CW (1.87 million).
