Going into this week, Anna Wintour was already one of the most powerful people in the magazine world. She has been the editor in chief of the United States edition of Vogue since 1988, the artistic director of Vogue’s parent, Condé Nast, since 2013, and the company’s global content adviser since 2019.

On Tuesday, as part of a larger revamping, Condé Nast announced that Ms. Wintour will have a pair of new titles — worldwide chief content officer and global editorial director of Vogue — giving her final say over publications in more than 30 markets around the world.

In addition to the elevation of its editorial leader, Condé Nast announced that Amy Astley, a confidante of Ms. Wintour, will be the global editorial director of AD, the title formerly known as Architectural Digest; Will Welch will become the global editorial director of GQ; and Divia Thani will be given the same role at Condé Nast Traveler.

Edward Enninful, the most powerful Black editor at Condé Nast, was made the head of Vogue’s editions in Britain, France, Italy, Germany and Spain. Simone Marchetti will become the European editorial director of Vanity Fair, putting him in charge of its editions in France, Italy and Spain. The American and British versions of Vanity Fair will remain under the control of Radhika Jones.
