World News Tonight Loses 25-54 Audience

ABC's World News Tonight saw a drop in the 25-54 demographic against NBC Nightly News during the first week of August, though it still led in total viewers overall. ABC News expanded its programming with a morning broadcast and, in a separate development, is pursuing a First Amendment case against the FCC in a dispute tied to Jimmy Kimmel, as primaries unfold and new research into mosquito control is highlighted.
