This book is about how journalism can contribute to the recovery of democracy from the crisis exemplified by the Trump presidency, the Brexit referendum and the rise of populism across the Western world. It explores the ethical concepts that provide the foundation for journalism in modern democracies: pluralism, liberalism, tolerance, truth, free speech, and impartiality. History has shown that crisis brings opportunity for change on a scale that is unachievable under ordinary political conditions, and this book proposes fundamental ways in which journalism can help democratic societies seize the moment. It traces the development of traditional mass media and social media and explores how the two might work better together to benefit democratic life. The development of press theory is described, and enhanced by a proposed new theory, Democratic Revival.
