This book examines a critical yet under-theorized area of contemporary business: the intersection of corporate social media and artificial intelligence (AI). It constructs a dual-framework?internal affairs and external affairs?that reframes corporate social media not merely as a communication tool, but as a strategic engine for organizational intelligence, coordination, and competitive positioning. Part 1 provides an introduction to the concept of AI-empowered corporate social media. Part 2 addresses the external affairs of corporate social media, including its role in shaping customer relationships, marketing narratives, and public trust. Part 3 turns inward, exploring how enterprise social media platforms are reshaping organizational knowledge flows, performance feedback, and collaboration. Through compelling historical analogies?from John Snow?s epidemiological breakthroughs to Toyota?s recall crisis?this book illustrates the dangers of drawing premature conclusions from spurious patterns. This critique is both timely and essential, especially as business leaders increasingly rely on opaque machine-learning systems for decision-making.
