New communication technologies have reshaped media and politics. But who are the new power players? The Hybrid Media System is a sweeping new theory of how political communication now works. Politics is increasingly defined by organizations, groups, and individuals who are best able to blend older and newer media logics, in what Chadwick terms a hybrid system. From American presidential campaigns to Wiki Leaks, from live prime ministerial debates to hotly contested political scandals, from the daily practices of journalists and campaign workers to the struggles of new activist organizations, the clash of media logics causes chaos and disintegration but also surprising new patterns of order and integration. The updated second edition features a new preface and an extensive new chapter applying the conceptual framework to the extraordinary 2016 U.S. presidential campaign, the rise of Donald Trump, and the anti-Trump resistance protests.
