NBC and ABC tied in the weekly prime-time ratings race last week, each averaging an 8.9 rating and 17 share, compared with CBS's 8.4/17.

A rerun of ABC's "Roseanne," the No. 1 program, aired the evening before its star, Roseanne Barr, screamed the national anthem before a San Diego Padres-Cincinnati Reds game.

Sunday night's CBS offering, Part I of "Murder Ordained," tied for third place with a rerun of NBC's "The Cosby Show."

Two of Fox Broadcasting's Sunday programs, "The Simpsons" and "Married ... With Children," ranking in the Top 20, were closely followed by "In Living Color," which tied for 21st place with "Real Life With Jane Pauley."

Fox wasn't so fortunate on Wednesday night when it tested the prime-time waters with "Hollywood Dog," "Molloy" and "Glory Days," finishing 88th, 89th and 90th, respectively, out of 90 programs for the week.

NBC won Wednesday, Thursday and Saturday nights; ABC won Tuesday and Friday nights; and CBS won Monday and Sunday nights for the week ending July 29.

In the network evening news race, "ABC World News Tonight With Peter Jennings" won with an 8.9/20, followed by "CBS Evening News With Dan Rather" with a 7.8/17 and "NBC Nightly News With Tom Brokaw" with a 7.6/17.
