Nielsen Business Media—which publishes Adweek, Brandweek, Mediaweek, Editor & Publisher and the Hollywood Reporter—is laying off "between 40-50 staffers," including people from the editorial departments of all of those publications. :( We've known Adweek's in trouble. They've cut back to 36 issues a year, lost staffers they haven't bothered to replace, and suffered under the regime of cruel editress Alison Fahey. Any more info on who's been hit? Let us know.
