Deadline says:
This is a nice vindication for a series that never had a permanent time slot or launch date, shuffled around the schedule and bounced between fall and midseason. Getting a last-minute upgrade to Thursdays from its original Saturday(!) time slot this fall, veteran CBS utility player Rules Of Engagement (3.7/12, 11.5 million) posted its best fall premiere in four years last night. Compared with last fall, when Rules aired Mondays at 8:30 PM, the veteran comedy was up 19%. Rules delivered far stronger numbers than the comedy it replaced, rookie How To Be A Gentleman, which posted a 2.5/7 in its last Thursday airing, and matched the demo performance in the Thursday 8:30 PM slot last week of a Big Bang Theory repeat.
Love The Big Bang and I'm glad Rules is back because I didn't like that other show they tried to put after Big Bang....it just didn't work...it was kinda stupid so I'm happy with the way it is now.
