How has the advent of new media affected free speech? How can we distinguish attacks on the media as “fake news” from legitimate critique? Are we all just listening to opinions we agree with, limited to media bubbles that had previously been broader and more porous? What are the conditions for free speech in different democracies - and can we learn from other countries' approaches to protecting freedom of speech under today's changed conditions? Has the deregulation of the media democratized knowledge and access, or is it leading to ever narrower viewpoints and perspectives? How is freedom of expression linked to the mainstream media editorial functions that once served as the arbiters of truth, for good and ill?
