Laurel Wentz, 43, was named international editor. She will oversee all international coverage, direct a network of global correspondents, and serve as a senior writer.
Ms. Wentz, who has been the London-based editor of Ad Age International for the last four years, will relocate to New York. She will also serve as editor at large for Ad Age International.
"In her expanded role, Laurel will considerably enhance Ad Age's global capabilities to reflect the globalization of advertising, marketing and media," said Ad Age Editor Scott Donaton.
Stefano Hatfield, managing and editorial director of Ad Age International, will serve as acting editor until a successor is named.
Separately, Laura Petrecca has been named deputy New York bureau chief for Ad Age.
Ms. Petrecca, 30, joined Ad Age in 1996 as a reporter covering ad agencies. Earlier this year, she added the sports marketing beat to her responsibilities.
In her new position as deputy bureau chief, she will edit stories and assist in managing the New York editorial operation. She will also continue to cover agencies and report on sports marketing.
"Laura's keen news judgment has made her a key member of Ad Age's reporting team. We're thrilled that she will now bring that talent to helping run the New York bureau," said Executive Editor George Vernadakis.
Prior to joining Ad Age, Ms. Petrecca was an editorial assistant at USA Today. She will report to New York Bureau Chief Ann Marie Kerwin.
