Kath Viner takes charge as The Guardian editor

British newspaper The Guardian announced Friday that Kath Viner, the head of its US operations, had been appointed to take over as editor-in-chief later this year. Viner becomes the 12th editor and the first woman to run the left-leaning daily in its 194-year history. She will replace Alan Rusbridger, who in 20 years as editor-in-chief has helped transform the paper from a traditional broadsheet to an international digital operation.
