Tonight, Jimmy Kimmel Live moves to 11:45PM from its previous 12:05AM timeslot. Much has been made of Kimmel's rivalry with Jay Leno. The question is who will win the battle for Nielsen dominance? Last quarter, Kimmel averaged a 0.5 adults 18-49 rating at 12:05AM while The Tonight Show averaged a 0.8. The heavily promoted premiere, featuring guests Jennifer Anniston and No Doubt, is likely to attract a larger than usual audience. So what do you think the rating will be?
