The Huffington Post has appointed New York Times editor Lydia Polgreen to succeed founder Ariana Huffington as its editor-in-chief.
Ms Polgreen had been with the New York Times for 15 years, where she most recently served as the associate masthead editor and the editorial director of NYT Global.
The 41-year-old called the Huffington Post job a "once-in-a-lifetime opportunity".
She said the media's "basic difficulty" in anticipating Donald Trump's election last month illustrates "the ways in which journalism has failed to reach beyond its own inner limits".
Ariana Huffington left the online news outlet in August.
