[10] After Bell took up an academic post in New York in April 2010, Gibson's responsibilities were expanded to include supervising all of Guardian News & Media's digital output.

[11] After several months of discussion with Alan Rusbridger in early 2011, Gibson was formally appointed the editor of the Guardian's new American online operations, to be based in New York, in April.

[15] She is reported to have told Alan Rusbridger when informing him of the scoops Greenwald, their newspaper's columnist, had uncovered: "I’ve got a little story to chat to you about".

According to one report in The New Yorker, internal politics related to her potential hiring led to the dismissal of that paper's executive editor, Jill Abramson a few weeks later.

[2][23] Under her editorship the website moved into more hard news and published an investigative series[24] in which 14 suspicious UK deaths (and 1 US) were found to have links to the Kremlin.

The series triggered Theresa May’s government to commit to a full review, was a Pulitzer Prize finalist and George Clooney has picked it up for a film.
