With new anchor David Miur, ABC’s World News Tonight won Premiere Week in the news demo (2.002 million viewers).

NBC Nightly News won Premiere Week in overall audience, with its biggest crowd in nine years — 8.187 million viewers. Brian Williams’ newscast also led with the younger, 18-49 age bracket (1.343 million). NBC noted its’ the fourth consecutive week, and 9th time in the past 11 weeks, that Nightly has grown its overall audience versus the comparable period from the previous year, and that the newscast grew versus same week last season with men in the news demo.

And yet, Nightly scored its smallest news demo crowd for the month of September (1.932 million) since at least ’92, while finishing first for the month with younger 18-49 year olds (1.443 million), which suggests the NBC newscast is losing ground with women in the news demo and with the 50-54 slice of that age bracket. World News Tonight won the month of September for the first time in 7 years in the news demo (2.085 million) — up 10% for the month, year to year.
