Carole Cadwalladr, the investigative journalist who rose to international fame last year after breaking the Cambridge Analytica scandal, will be making her first appearance at the TV Festival on Wednesday.

In conversation with Canadian broadcast journalist Richard Gizbert from Al Jazeera’s The Listening Post, the Pulitzer-nominated writer will be discussing the responsibility of mainstream broadcasters in holding power to account, the new dark power of tech titans and new media’s involvement in public thought and polling. Following her appearance in Netflix’s The Great Hack, Cadwalladr will discuss what can be learnt and changed by keeping these dangers in the public eye and how we continue to scrutinise mainstream media.

Following on from the themes in her viral TED Talk where she took down and ruffled the tech giants from within their own conference, Cadwalladr asks what the fast-moving industry we work in can do to fix a problem that has broken the very concepts of democracy, responsibility and impact.
