Alcatraz Fox TV RatingsIn its second week against new competitor The Voice, ABC’s reality veteran Dancing With The Stars (3.1/8, 17.6 million) was down 11% from its season premiere last Monday, which was the lowest-rated ever in the franchise’s history. Dancing still was the most-watched program of the night by a mile. At 10 PM, Castle (2.4/6) was even with last week’s fast national. (Compared with the final it was up 4%, but those comparisons are irrelevant since Castle‘s fast nationals are always inflated by a Dancing overrun and are adjusted down in the finals.) NBC’s The Voice (4.4/12, 11.8 million) was down a tenth from last week’s fast national to a season low, and Smash (2.2/6) was flat.

Fox aired a two-hour season finale of Alcatraz (1.5/4), which didn’t make a case for renewal — down a tenth from last week’s hourlong episode to a series low. With CBS in repeats, NBC and ABC split the honors for the night, with NBC (3.7/10, 10 million) taking the demo crown and ABC (2.9/8, 15.8 million) No. 1 in total viewers. The CW aired Confessions Of A Shopaholic.
