Robert Dowling resigned Tuesday as editor-in-chief and publisher of the Hollywood Reporter. Today's (Wednesday) Los Angeles Times attributed his departure, which will become effective on Dec. 31, to upheavals at the trade paper's parent company, Dutch-based VNU, whose CEO, Rob van den Bergh, stepped down last month after losing a battle with activist shareholders. Alex Ben Block, the editor of the trade publication Television Week, who worked for Dowling as an editor for eight years, remarked, "Changes at the top of VNU have rocked the whole company and may have been a precipitating factor." Dowling himself told the Times: "Nobody was the catalyst; it just kind of got to that spot."
