With evening news ratings no longer an NBC walkover, news divisions this morning sent out unusually yeasty memos about ratings for the July sweep period.

ABC News boasted ABC World News won the July sweep in the news demo, taking back-to-back sweeps among 25-54-year-olds for the first time in seven years. The ABC newscast, officially anchored by Diane Sawyer for about one month more,  was the only program in its genre to improve in the news demo and among 18-49 year-olds, the division crowed, while its competitors all dropped. ABC’s newscast clocked 1.883 million news-demo viewers, to NBC’s 1.802 million and CBS’ 1.466 mil. Last July sweep, the ABC newscast finished second in the news demo clocking 1.818 million viewers, to NBC’s 1.991 million.

DIANE SAWYERNBC News, meanwhile, bragged this July marked NBC Nightly News’ 28th consecutive sweep win in overall audience, with 7.786 million viewers — 408,000 more viewers than ABC’s 7.378 million and 1.732 million more than CBS’ 6.054 mil.  NBC also countered that Brian Williams’ newscast added 83,000 viewers compared to the previous July ratings derby, including a 13% hike among 18-49-year-old guys. (NBC’s newscast also posted gains with teens and viewers 50-plus.)

While conceding ABC’s newscast edged it out in the news demo, NBC pointed to its sweep win among 18-49 year olds — 1.322 million to ABC’s 1.279 mil.  NBC’s newscast has finished first in the younger demo ratings for 29 straight sweeps periods.
