NBC came out on top in the ratings last week with help from its new comedy "Blossom." But the premiere of its "Real Life With Jane Pauley" wound up near the bottom when football on CBS ran into prime time.

NBC had a 13.2 rating and CBS a 13.1, the A.C. Nielsen Co. reported. ABC was well behind with an 11.6. Each ratings point represents 931,000 homes.The top-rated show, with a 24.4, was NBC's "Cheers," a frequent winner this season.

CBS' New Orleans Saints-Chicago Bears playoff had a higher rating, a 26.9, for the 21 minutes the football game overlapped into prime time. But it wasn't counted among the week's shows because it didn't start in prime time.

Still, the game delayed the start of CBS' powerhouse "60 Minutes," pitting it against the premiere of Pauley's new series. It was no contest.

CBS' broadcast was the week's second most-watched show. Pauley's effort wound up in 70th place with a 7.3 rating.

Her show was followed by the premiere of "Expose" with Tom Brokaw. The two newscasts are NBC's latest effort to compete in the 8-9 p.m. EST slot on Sundays. "Expose" fared slightly better in its debut. It had a 9.6 rating.

A Thursday preview of NBC's "Blossom" was third in the week's ratings. The show began is regular Monday run this week.
