ABC's "World News with Diane Sawyer" scored its first weekly ratings win of the season in the key news demo, ranking as the top evening news program for the week of April 7 in viewers 25-54, Deadline.com reports.

It marked a rare win over "NBC Nightly News with Brian Williams," with the ABC program winning by 12,000 viewers in the demo — 1.882 million vs. 1.870 million. The demo win was the first for ABC since the week of July 22, 2013, the report notes.

"Last July — one year after ABC’s 'Good Morning America' snapped NBC’s 'Today' show weekly winning streak, ABC’s evening newscast outstripped NBC’s in the news demo by 38,000 demo viewers, ending NBC’s newscast’s ratings winning streak of nearly five years," the report notes.

The piece adds that during the week of April 7, "Sawyer’s newscast covered breaking news — high school stabbings in Pennsylvania, California bus crash, Terry Moran in Central African Republic with UN Ambassador Samantha Power covering refugees and violence — but the newscast also featured a broadcast exclusive with 'Mad Men' stars and creator as they debuted the AMC series’ final season."

The ABC news program also reached a milestone on Facebook during the week, rising to 1 million likes.

The report adds: "ABC’s was the only broadcast up in the demo from one year ago during the comparable week (1%) — NBC’s newscast tumbled by 18% and CBS’s Scott Pelley-anchored newscast dropped 10% in the demo."

When ABC's evening news show won the weekly demo back in July 2013, it was the first time since November 2008, which in turn was before Sawyer took over the anchor chair from Charlie Gibson in 2009.
