After hitting a series low 1.6 in the demo last week, 30 Rock plummeted even further to a 1.3 this week. That time slot is just absolute death considering that shows have to go up against both American Idol and The Big Bang Theory which are the #1 and #2 shows in the demo currently, I believe. Big Bang Theory in particular has been hitting series high numbers lately.
Furthermore, Up All Night slipped to a 1.8 despite having The Office as a lead-in (although it should be noted that The Office also fell to a low last night as well). Anyway, this is some good news for Community fans after Whitney/Chelsea did surprisingly well two nights ago.
