New York Post: The ABC/NBC news-ratings war between David Muir and Lester Holt is about to get even more intense. ABC’s evening broadcast, “World News Tonight with David Muir,” took its first-ever win for a full year in the all-important C3 Nielsen ad ratings. Muir beat “NBC Nightly News” — anchored by both Brian Williams and Lester Holt over the past 12 months — by a hair in the key category of C3 adults 25 to 54 years old, ABC said. The network is about to start an ad campaign touting its win.
