In this groundbreaking new series hosted by Niall Ferguson and based on his bestselling book The Square and the Tower, Ferguson visits network theorists, social scientists and data analysts to explore the history of social networks. From the Reformation and 17th century witch-hunting, through the American Revolution and to the nightmare visions of Orwell’s 1984, Ferguson explores the intersection of social media, technology and the spread of cultural movements. Reviewing classic experiments and cutting-edge research, Ferguson demonstrates how human behavior, disruptive technology and profit can energize ideas and communication, ultimately changing the world.
