Mark Frankel is Social Media Editor at BBC News. In this in-depth interview, he discusses how for millions of people the news is now increasingly broken (and made) on Twitter; the importance the BBC places on accuracy over speed, and the editorial challenges created by each of the various social platforms; how the breaking news alerts are managed technically; how their use of live streaming allows them to engage with audiences in new ways; dealing with trolls, abuse, and the politics of fake news; and gives his thoughts on what’s next for BBC News - arguing social media will ultimately overtake not only broadcast, but the other online platforms too.
