We are living in a modern world where falsehood regularly seems to overwhelm truth. The ability of billions of people to publish has created a vast amount of unreliable and false news which now competes with and sometimes drowns more established forms of journalism. So where can we look for reliable, verifiable sources of news and information? What does all this mean for democracy? And what will the future hold? Reflecting on his twenty years as editor of the Guardian at a time of unprecedented digital disruption; and his experience of breaking some of the most significant news stories of our time, Alan Rusbridger answers these questions and offers a stirring defence of why quality journalism matters now more than ever.
