Unforgettable — the highest-rated new drama of the 2011-12 TV season's first week — apparently isn't memorable enough for some people to return to.
The show's third episode attracted 11.35 million viewers and nabbed a 2.4 rating among industry-prized 18-to-49-year-olds, overnight Nielsen ratings showed. It drew 19 percent fewer viewers two weeks after its debut, and last week it fell behind Person of Interest as the most popular new network drama.
It still emerged victorious in prime time's final hour Tuesday against Body of Proof, which went against the grain by improving (10.22 million/2.1 — up 11 percent and 17 percent, respectively), and Parenthood (5 million/2.0 — down 9 percent).
The first new show to earn the assurance of full season— New Girl — lured 8.62 million people and posted Tuesday night's high demo rating: 4.3. While sustaining Fox's faith, the show also trended downward for the third week (vs. 9.26 million/4.4 rating last week, and 10.98 million for the premiere).
Glee grabbed 8.30 million viewers and 3.5 demo rating (vs. last week's 8.34 million/3.6 and 8.91 million/3.8 for the Season 3 premiere).
And if it's Tuesday, it means CBS has won the first two hours of prime time with NCIS, which attracted 18.86 million (4.1) and NCIS: Los Angeles, which lured 14.65 million (3.6). At 9:30/8:30c, Fox's Raising Hope defied the downward trend by reaching 6.51 million people.
Against NCIS and Glee at 8/7c, the first hour of Dancing with the Stars entertained 9.11 million viewers vs. The Biggest Loser on NBC (5.52 million) and The CW's 90210 (1.32 million — down 16 percent).
At 9/8c, the DWTS results drew 14.83 million vs. Loser (5.69 million) and the fourth round of Ringer, which, after nabbing 2.01 million last week, got just 1.49 million — its lowest yet and far below the 2.7 million for its premiere.
Numbers also may have been down because many eyes, particularly in the nation's largest TV market, were turned to the playoff game between the New York Yankees and Detroit Tigers. Some 7.01 million fans watched the prime-time game on TBS, making it the most watched division-series contest in four years.
