Monaco and Woolley offer the first comprehensive overview of the history of bots, tracing their varied applications throughout the past sixty years and bringing to light the astounding influence these computer programs have had on how humans understand reality, communicate with each other, and wield power. This book examines the role bots play in politics, social life, business, and artificial intelligence. Despite bots being a fundamental part of the web since the early 1990s, the authors reveal how the socially oriented ones continue to play an integral role in online communication globally, especially as our daily lives become increasingly automated.
