Most original broadcasts posted small drops on Monday night, with only the CW posting modest gains thanks to the 100th episode of Gossip Girl.

Fox won the night, though. The net had new episodes of House and freshman drama Alcatraz, both of which dropped 10 percent in adults 18-49, according to fast affiliate ratings. The duo scored respective 2.8 and 2.7 ratings in the target demo, giving the net an average 2.8 and 8.5 million for the night.

CBS' Monday block, still in repeats, brought in a 2.3 in adults 18-49, also losing to Fox in total viewers with 8.1 million. A repeat of Two and a Half Men (3.0 rating in adults) was the night's strongest broadcast across the board.

The Bachelor dropped just 4 percent after last week's jump, pulling a 2.6 in adults 18-49 for the two-hour broadcast. Adding a repeat of Castle, ABC averaged a 2.2 rating for 18-49-ers and 7.6 million for the night.

Who's Still Standing? aired even with the previous week's 1.7 in the demo, while an encore of Fear Factor pulled a 1.5 in 18-49-ers and the debate-less Rock Center With Brian Williams dropped 50 percent from its super-sized telecast last week for a 0.8. Overall, NBC brought in a 1.3 in the demo and 4.6 million viewers.

On the CW, Gossip Girl's episodic centennial marked its second most-watched episode of the season, up 17 percent in adults 18-49 for a 0.7. Hart of Dixie reaped the benefits climbing 20 percent in adults for a 0.6 -- also the net's average showing in the 18-49 demo for the night.

More to come.
