Vogue remains fashion鈥檚 flagship magazine but, like many print publications, has struggled to adapt to the digital era.
Wintour was known for decisive leadership, such as axing work without discussion, and as a fixture in the front row at catwalk shows with her unchanging bob haircut.
A 2015 documentary 鈥淭he September Issue鈥 about the magazine pointed to her ice queen image and steely ambition but also revealed a warmer human side.
Wintour has for many years also run the Met Gala, an extravagant Manhattan fundraiser that attracts an A-list of dressed-up stars from the worlds of fashion, film, politics and sports.
As Conde Nast鈥檚 chief content officer, she will continue to oversee publications including Vogue, Wired, Vanity Fair, GQ, Conde Nast Traveler and Glamour.
For many years, Wintour declined to comment on 鈥淭he Devil Wears Prada,鈥 which was written by one of Wintour鈥檚 former assistants, Lauren Weisberger.
But when it was turned into a musical and opened in London in 2024, she told the BBC that it was 鈥渇or the audience and for the people I work with to decide if there are any similarities between me and Miranda Priestly.鈥
Explaining her sunglasses, she told the outlet that 鈥渢hey help me see and they help me not see. They help me be seen and not be seen. They are a prop, I would say.鈥
