The third Sunday of the May sweep was a competitive one among the major networks, according to preliminary nationals from Nielsen, primarily because there were no standout performers. The Big Four were all within three-tenths of each other in the key demo of adults 18-49.

ABC, which took the night in 18-49 by a tick over CBS in the prelims, won both hours from 7 to 9 in the demo with “America’s Funniest Home Videos” (2.6/9 in adults 18-49, 7.7 million viewers overall) and “Extreme Makeover: Home Edition” (4.3/12 in adults 18-49, 10.7 million viewers overall). Net wasn’t as strong with the return of “Super Millionaire” at 9 (3.5/9 in adults 18-49, 11.6 million viewers overall) and the series finale of “The Practice” at 10 (3.5/9 in adults 18-49, 10.8 million viewers).

At CBS, its new three-hour version of “Helter Skelter” did OK (4.1/11 in adults 18-49, 9.3 million viewers overall), winning the 10 o’clock hour in 18-49 and producing the net’s best made-for 18-49 result since December.

Fox led in 18-49 at 8 o’clock with “The Simpsons” (4.1/12 in adults 18-49, 8.3 million viewers overall) and was competitive at 8:30 with a repeat of “That ’70s Show” (3.9/11 in adults 18-49, 7.5 million viewers overall) and at 9 with “Malcolm in the Middle” (3.8/9 in adults 18-49, 7.5 million viewers overall).

NBC was paced as usual by dramas “Law & Order: Criminal Intent” (first-place 4.3/11 in adults 18-49, 13.3 million viewers overall) and “Crossing Jordan” (4.3/11 in adults 18-49, 13.0 million viewers overall).

Preliminary 18-49 averages for the night: ABC, 3.5/10; CBS, 3.4/10; Fox, 3.3/10; NBC, 3.2/9; WB, 1.6/5.
