Facebook's global ads chief Carolyn Everson quits

The announcement came through a post she shared on the social media platform on Wednesday.

"We wish Carolyn the best as she moves into a new chapter. We are grateful for her contributions," said a Facebook spokesperson in an emailed statement.

Everson, who had been at Facebook more than a decade, was vice president of Facebook's Global Business Group. She was a key spokesperson for the company when more than 1,000 advertisers joined a Facebook boycott last summer over concerns it was not doing enough to combat hate speech on the platform.

The company said Nicola Mendelsohn, who runs the EMEA region of this division and has been at the company eight years, will be the new interim leader of the Global Business Group.
