ABC showed who is the king of Sunday night, vanquishing CBS movie “Elvis” and everything else in its path en route to a dominant ratings victory.

Despite a typical Mother’s Day drop in early evening television usage, ABC megahit “Desperate Housewives” was as strong as ever, and hot newbie “Grey’s Anatomy” hit new highs, teaming with “Extreme Makeover: Home Edition” to help the Alphabet notch its seventh straight Sunday triumph — and its second in the May sweep.

CBS, meanwhile, did just so-so with part one of two-part biopic “Elvis,” and Fox’s animation lineup declined from its strong start but held up pretty well, remaining second in key demos.

According to preliminary nationals from Nielsen, “Desperate Housewives” (roughly 11.5 rating/27 share in adults 18-49, 26.5 million viewers overall) will stand as the night’s — and week’s — top program in 18-49, matching the combined CBS-NBC-Fox delivery in the 9 o’clock hour.

“Grey’s Anatomy” again impressed (roughly 8.5/22 in 18-49, 18.8 million), hitting series highs in most categories and beating CBS and NBC combined in 18-49.

As for “Elvis,” it built throughout its two hours but settled for a prelim 3.9/9 in 18-49 and 13.9 million viewers overall — up 30% from the CBS Sunday Movie average in 18-49 (3.0/7), but less than stellar for the net’s marquee movie event of May.

“Elvis,” which concludes Wednesday, was on par with the net’s recent “Locusts” and “Spring Break Shark Attack,” suggesting there may be a ceiling the Eye will hit with its movies — regardless of their pedigree — opposite ABC’s hot lineup.

Over at Fox, its hour of firstrun “The Simpsons” (prelim 4.2/12 in 18-49, 9.2 million) was down about 20% from the previous week, placing a distant second in demos to ABC’s “Extreme Makeover: Home Edition” (prelim 6.0/17, 14.8 million).

At 9, “Family Guy” (4.5/11 in 18-49, 9.7 million) similarly was off about 20% week-to-week, but it was a solid second to ABC in most key demos, and “American Dad” followed at 9:30 (3.7/8 in 18-49, 8.2 million) with similar retention to its premiere.

NBC was on the high end with “Dateline” (2.1/8 in 18-49, 5.7 million) and “The Contender” (2.8/8, 6.1m), but again couldn’t do much from 9 to 11 with “Law & Order: CI” (3.5/8, 11.1m) and “Crossing Jordan” (3.6/9, 11.5m).

For the night, ABC’s prelim 7.1 rating/20 in 18-49 topped Fox (3.5/10) and CBS (3.2/9) combined, with NBC placing fourth (3.0/8). ABC also led in total viewers (16.9 million to 13.2 million for CBS). ABC also has won 12 straight Sundays in adults 18-34.
