VIDEO : ABC?s David Muir Tops NBC?s Lester Holt In Weekly TV Ratings

?World News Tonight? with anchor David Muir just topped NBC?s ?Nightly News? with Lester Holt in weekly TV ratings for the first time in nearly two years. The ABC News program won the key age 25 to 54 demographic, the 18 to 49 demo, and total viewers last week. ABC?s victory snapped a 21-month, 89-week demo win streak for NBC News. It also did not hurt the Monday-Friday results that the Oscars had aired on Sunday.
