Magazine legend Anna Wintour is stepping down as editor of fashion bible US Vogue after 37 years in the post, US media reported Thursday.

British-born Wintour, 75, has been one of the most influential and formidable figures in fashion and magazine journalism for decades, famous for her ever-present sunglasses and unchanging bob haircut.

She was widely seen as the inspiration behind "The Devil Wears Prada," a hit 2003 novel and 2006 movie, in which the role of a tyrannical magazine editor was played by Meryl Streep.

Wintour, who took the helm at US Vogue in 1988, announced her departure at a staff meeting, but she will stay on as group owner Conde Nast's global chief content officer and as editorial director at Vogue, People magazine reported.

Several other publications also reported this news.

Wintour, who held the title of Vogue's editor-in-chief, was made a British dame in 2017 and in February this year was made a companion of honor, joining a select group never numbering more than 65 recognized for major contributions in their field.

At the ceremony in London in February, she removed her trademark sunglasses to receive the award and said she had told King Charles III that she had no plans to stop working.

Wintour, who was raised in the UK by a British father and an American mother, is described by many as the single most powerful person in the global fashion industry.

Her choice of covers for the monthly magazine was seen as authoritative in the publication's heyday, and she was renowned for her strict control over content, sometimes axing work without discussion.

A 2015 documentary about her life pointed to her ice queen image and steely ambition but also revealed her warmer side.
