There's a pretty good post on the BBC The Editors blog featuring a video that highlights some of the changes brought by social media to their newsroom. It includes shots of the BBC "UGC Hub"( User Generated Content).
"Many of our leading journalists and presenters now incorporate social media platforms into their work: Tim Willcox; Lyse Doucet; Robert Peston and until recently Laura Kuenssberg (who has now been joined by her Twitter followers, with our blessing, at ITV News).
We've innovated, experimenting with branded hashtags to curate coverage; visualising Royal Wedding day tweets on our website; and work is under way to seamlessly integrate field despatches from our correspondents and reporters into our core news services and social media output.
And like many established news providers, we have created an open and modern set of guidance to help our staff engage, gather news and spread their journalism, working within the BBC's editorial values that are at the core of our journalism."
