ENTERTAINMENT : NBC Wins Prime-Time Ratings Race

NBC won the prime-time ratings race for the fourth consecutive season and by the second-largest margin ever, according to figures released today.

ABC came in second and CBS was a close third.

The ratings figures for the 1988-89 network television season confirmed the expected NBC win, as well as the fact that its “The Cosby Show” was the top-rated program for the fourth straight season--only the third network show to make three in a row. The other two were “Gunsmoke” and “All In the Family,” both CBS. Archie Bunker did it five times straight.

ABC’s “Roseanne,” which came in second in overall ratings, was the top-rated new show of the season.
