Scholars have recognised that uncertainty and insecurity about the true nature of the world lie behind belief in conspiracies. People , power and politics are the key to understanding the proliferation of conspiracy theories in the modern world via the media and, as it stands, the three terms that appear in the subtitle of this book. This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book provides a short overview of how the form and dissemination of conspiracy theories have been historically intertwined with the evolution of communication technologies, before taking a deep dive into the contemporary media environment, and the ways in which this facilitates the spread of conspiracy theories. It outlines the network’s history, explaining the Kremlin’s motivations behind its creation, and the reasons that RT developed into a media outlet focused specifically on the spread of conspiracy theories.
