Episodic reruns and reality shows handed CBS a decisive win in last week's ratings.

But fresh reality fare served all the networks well. The Tuesday edition of NBC's "America's Got Talent" was the week's most-watched show, followed by ABC's "The Bachelorette" and the Wednesday broadcast of "Talent" ranking third, the Nielsen Co. said.

Two airings of "Wipeout" ranked fifth and sixth for ABC, and three editions of CBS' "Big Brother" landed comfortably in the top 20.

Even so, repeats of CBS' "NCIS," "The Big Bang Theory," "Two and a Half Men," "The Mentalist" and "60 Minutes" all placed in the top 10.

For the fifth consecutive week, CBS dominated in total prime-time audience, averaging 5.9 million viewers. ABC and NBC were virtually tied with 4.99 million and 4.96 million, respectively. Fox was next with 4.5 million. ION had 1.2 million, and the CW had 1.1 million.

Among the evening newscasts, NBC's "Nightly News" was on top, as usual, but ABC's "World News" narrowed the viewer gap to its smallest margin this season. NBC logged 7.37 million, while ABC was 360,000 viewers behind with 7.01 million. The "CBS Evening News" had 5.01 million.
