Fox experienced a ratings toon-up on Sunday night thanks to its Animation Domination block of programming, with "The Cleveland Show" and "Family Guy" winning their time slots in the 18-49 demographic, and relative newcomer "Bob's Burgers" making modest gains, according to preliminary numbers.

"Bob's Burgers" at 8:30 pulled a 2.26 in the demo — a 10 percent increase over its previous airing — and 44 million total viewers. "Family Guy" pulled in a 3.4/9 in the demo at 9, up 10 percent from its last airing of a new episode on March 6, and a total viewership of 6.6 million. "The Cleveland Show" grabbed a 13 percent ratings increase in the demo over last week, with a 2.7/7 and a total viewership of 5.5 million.

CBS's primetime schedule was skewed by overrun from the NCAA championships, causing spillover across time slots. At 8, "60 Minutes" and "The Amazing Race" combined to draw a 2.4/7 in the demo and 11 million total viewers, while the 8:30 continuation of "The Amazing Race" pulled a 2.7/7 with 9.7 million viewers.

"The Amazing Race" continuation and "Undercover Boss," at 9, drew a 2.7/7 in the 18-49 demo, with 10.7 million total viewers; "Undercover Boss," at 9:30, also captured a 2.7/7 share in the demo, but garnered 11 million total viewers. The remainder of "Undercover Boss," combined with the start of "CSI: Miami," pulled a 3.0/8 in the demo, with 12.3 million total viewers, and "CSI: Miami" in the 10:30 slot drew a 2.5/7 in the demo, with 10.6 milllion viewers.

ABC's "Secret Millionaire," at 8, grabbed a 2.4/7 in the demo, with 10.2 million viewers. The following hour, "Shark Tank" took a 1.9/5 in the demo, with 6.2 million viewers, while the season finale — and possibly series finale — of "Detroit 187" managed a 1.1/3 with 4.7 million total viewers. That represents a drop from its last telecast on March 15, when the show drew a 1.2/4 with adults 18-49, and 5.6 million total viewers.

At NBC, "America's Next Great Restaurant" at 8 found a 1.2/4 in the 18-49 demo, while "Celebrity Apprentice," from 9-11, took in a 2.8/7, with 8 million total viewers.
