Two long-running series, Fox’s 24 and NBC’s Law & Order, made a quiet exit last night. The two-hour series finale of 24 posted a 2.7 rating/8 share among adults 18-49. That was down 10% from last week and down 13% from last season’s finale. Law & Order, in its final original airing, at least on NBC (Creator Dick Wolf has been having conversations with TNT about moving the series there), drew a 1.9/5 at 10 PM, up 12% from last week and down 5% from last season’s finale. This was the veteran crime drama’s best ratings result since March 1.

Probably relieved that their show has been renewed, Chuck fans didn’t show up in droves for the season finale. The two-hour closer of the NBC spy dramedy that led into L&O drew a 1.8/5 in 18-49, the show’s lowest-rated telecast ever and down 25% from last season’s finale. ABC’s Dancing with the Stars (4.0/12) was down 2% from last week, while The Bachelorette (2.8/8) was down 7% from last year’s May premiere, logging the franchise’s lowest-rated season debut.

The season finales of CBS’ Monday lineup were solid, all up from last week by double digits. How I Met Your Mother opened the night with a 3.5/11, followed by Rules Of Engagement (3.3/9), Two and a Half Men (5.0/13), The Big Bang Theory (5.2/13), in its last original airing on Mondays before it moves to Thursday in the fall, and CSI: Miami (3.3/9). All series were down slightly from last year’s finales with the exception of Rules and Big Bang, which were down 25% and up 41%, respectively, as they switched time slots this season (Rules aired behind Two and a Half Men last year, while Big Bang ran at 8:30 PM). CBS (3.9/11, 11.9 million viewers overall) was No.1 for the night in adults 18-49, while ABC (3.2/9, 12.5 million) was tops in viewers.
