Twitter's head of news exits

Just a year after taking on her role at Twitter as the head of news, Vivian Schiller is stepping down. Twitter VP of global media Katie Jacobs Stanton will in the mean time take up her responsibilities as part of an internal reorganisation.

Schiller (pictured) announced the move in a series of tweets.

Prior to taking on her role at Twitter, Schiller was the chief digital officer at NBC News.
