Coles is expected to leave by the end of this week. Her departure follows the elevation of of Troy Young, Hearst’s digital media chief, as president of the media giant’s magazine division.
Best known for her former roles as editor-in-chief of Marie Claire and Cosmopolitan before subsequently being placed in charge of content for all 300 magazine titles. Coles is believed to have quit rather than have her authority undermined.
Coles was elevated to the newly created role of chief content officer in September 2016 with a remit that included all printed products as well as the development of television shows such as Freeform’s The Bold Type.
In 2016 Coles joined the board of Snapchat as its sole female director.
