ABC’s World News (now back to being called World News Tonight) was last week’s No. 1 newscast in the news demo, as well as 18-49, with its largest margins since 2007. In the news demo, ABC clocked a 271,000 viewer lead over NBC, and a 494,000 edge over CBS Evening News.

Now, some fine print:

Nightly News – anchored by Lester Holt all week while Brian Williams was off — was not rated on Monday night due to the Emmy Awards airing live on NBC across the country, gumming things up for the newscast in western markets; it was the first Monday Emmycast since the mid 70’s. That helped boost ABC’s audience for the night – it’s Monday audience was 582,000 viewers bigger than its Tuesday crowd, and 1.2 million viewers bigger than its audience to its biggest audience of the week, besting even Diane Sawyer’s final night on Wednesday. While conceding the demo derbies, NBC’s newscast has clocked the largest overall audience for 259 consecutive weeks.
