For the eighth time in the 11-week-old television season, more Americans bellied up to the bar of NBC's "Cheers" than any other show on television. Last week they saw double.

A repeat of the hit comedy series was the most watched program in the country, helping the network win the week with a 13.1 average rating.ABC was second with 12.4, just one-tenth of a ratings point ahead of CBS with 12.3, according to figures released by the A.C. Nielsen Co.

Each ratings point represents 931,000 homes.

NBC's victory was aided by Sunday's "Hallmark Hall of Fame" presentation of "Decoration Day" starring James Garner, which finished seventh.

The CBS Sunday news magazine "60 Minutes" was No. 2, followed by NBC's "A Different World." Roseanne Barr and her bickering brood on ABC's "Roseanne" were No. 4.

NBC's "The Cosby Show," which suffered its first loss last week to the animated antics of Fox Broadcasting Co.'s "The Simpsons," was back on top. The Cos finished fifth while a "Simpsons" repeat plummeted the series to 44th place.

In the prime-time news wars, ABC and Peter Jennings ranked first yet again with an 11.7. NBC and Tom Brokaw were second with 10.1, edging just ahead of CBS and Dan Rather with 10.

Here are the top 10 shows, their network and rating: "Cheers," NBC, 20.4; "60 Minutes," CBS, 19.8; "A Different World," NBC, 18.6; "Roseanne," ABC, 18.3; "The Cosby Show," NBC, 18.1; "Murder, She Wrote," CBS, 18; "Hallmark Hall of Fame: Decoration Day," NBC, 17.9; "Murphy Brown," CBS, 17.8; "Empty Nest," NBC, 17.6; "Matlock," NBC, 17.3.
