SpoilerFix (don't click the link--they've got info on the last episode that you don't want) is reporting that 24's been renewed, and is moving to Mondays. The premiere will apparently be two hours long, and all 24 episodes will run without preemption, all in a row, for 23 straight weeks.

This is the new thing the networks are doing--ABC is doing the same thing with Alias next January. It seems like it's a first step towards year-round programing, with 2 or 3 seasons of about 20 weeks each. It's also quite clearly an attempt to stop the viewership bleeding that long stretches of reruns cause, particularly with mythology-heavy shows like 24, Alias, or (sigh) Angel.

I say good on them. I'm surprised no one's tried this before now.
