The second show of the second week of American Idol (5.1/4) found the judges taking in auditions in Randy Jackson’s hometown of Baton Rogue, LA. The first one-hour episode of Season 12 dominated the demos and was seen by 15.53 million but dipped 6% from the January 17 show’s 8-9 PM slot —  the same drop compared with fast nationals from the January 26, 2012 show. So far, Idol’s season-to-date four-day average is down 12% year-over-year. Over the same period, Season 11 was down 27% compared with Season 10. With a solid Idol as a lead-in, Glee (2.7/7) came raging back from its winter break, up 35% from its last original December 13. With 11.214 million watching, Fox won the night in overall viewers (11.214 million) and the adults 18-49 demo.

ABC’s freshman series Last Resort (1.2/3) wrapped its abbreviated season and run last night. Cancelled in November, the military drama went out strong, up 20% from last week’s series low. Grey’s Anatomy (3.08) was flat with its January 17 show, and political drama Scandal (1.8/5) was a repeat. However, in the encore universe, it was the show’s best repeat, beating out  the January 3 show’s 0.9 rating.

On the second-to-last show of its seven-season run, 30 Rock (1.4/4) rose 8% from last week on NBC. That matches the show’s secondhighest rating of the season. With 3.838 million watching, 30 Rock also scored its highest total viewership of the season. In its second week in the 8:30 PM slot, Parks And Recreation (1.7/5) fell 11%. The Office (2.0/5) was also down, with a slip of 5% from its January 17 show. After cratering 25% last week, NBC’s new White House comedy 1600 Penn (1.3/3) saw a slight 8% rise last night. The same could not be said Rock Center With Brian Williams (0.8/2), which fell 27% from last week, tying a season low.

CBS was all encores last night with The Big Bang Theory (3.1/9), Two And A Half Men (2.3/6), Person Of Interest (1.9/5) and Elementary (1.5/4). The Big Bang repeat was the second-most-watched show of the night, pulling in 11.5 million viewers. The CW had The Vampire Diaries (1.3/4) and Beauty And The Beast (0.7/2) last night.
