The finales of Fox’s “24” and CBS’ “CSI: Miami” highlighted the final Monday of the season, which saw Fox prevail in adults 18-49 and CBS in adults 25-54 and total viewers, according to preliminary nationals from Nielsen.

From 8 to 10, “24” (5.1 rating/13 share in adults 18-49, 12.1 million viewers overall) won in key demos as well as total viewers, capping a comeback season for the real-time thriller. For the season, it was up about 15% from last year despite losing its “American Idol” lead-in and shifting to a new night.

CBS ruled at 10 with “CSI: Miami” (7.1/18 in 18-49, 20.5 million viewers overall), which bested the season finale of NBC’s “Medium” (4.5/11 in 18-49, 11.9 million viewers overall). ABC didn’t do a whole lot with its 9-11 p.m. spec “Nick & Jessica: Tour of Duty” (2.4/6 in 18-49, 6.1 million viewers overall).

The Eye’s comedy block suffered with the departure of “Everybody Loves Raymond,” but was paced by an hour of “Two and a Half Men” from 9 to 10 (4.6/11, 14.5 million viewers overall). “Men” led in total viewers with an original at 9 and a repeat at 9:30.

NBC ran second in demos at 8 with its fading “Fear Factor” (3.4/10 in 18-49, 8.3 million viewers overall) and placed third at 9 with the season finale of “Las Vegas” (3.9/10 in 18-49, 10.9 million viewers overall).
