In Media and the Power of Knowledge, Fuller traces the evolution of how the media has transformed global and social knowledge. The book draws a line from the printing press to the rise of electrical and electronic communication, and analyses how the emergence of our public sphere has developed.

Fuller points to the spread of publishing and the rise of technology such as telegraphy that allowed researchers to connect, and allowed the first forms of collective intelligence to flourish. With the invention of the internet, globally accessible information has become possible and has fundamentally altered how we form public opinion. Media and the Power of Knowledge also looks at the role of media moguls and the function of the critic, pundit and broadcaster, and investigates how the balance of power has shifted in recent years.

Clearly structured and presenting provocative arguments, this book considers the likely future developments of the media and its far-reaching implications for the human condition.
