"[A] timely dive into an industry in tumult. . . . Auletta, a veteran New York writer who has covered both Wall Street and the media for decades, does a remarkable job of digging into the personalities and the covert deals."--Financial Times

"Auletta masterfully maps the rapidly evolving topography of the advertising industry. . . . Perhaps most prescient is Auletta's spot-on analysis of the interplay between traditional and social media. . . . Other fascinating topics include how efforts such as Citibank's Citi Bike bike-sharing program in New York City and YouTube Red represent new forms of advertising; how Facebook fell prey to Russian attempts to influence the 2016 U.S. presidential election; and how smartphones have revolutionized advertising. Intelligent and well researched, Auletta's lively survey serves as an excellent primer to a brave new world."--Publishers Weekly

"Auletta delves into how disruptions are impacting the most powerful agencies and personalities in the business and changing the way advertising is bought, sold, and created. With journalistic precision, the author profiles the executives and companies that have dominated the advertising, marketing, and media industries over the past decade before pivoting to describe how relatively new influencers such as Facebook and Google have overturned conventional thinking."--Library Journal

"However distant, even repugnant, the advertising and marketing business might seem to the average consumer, it is the fuel that drives a First World economy, Auletta argues. . . . Astute, colorful, fully informed. . . . an important if utterly disquieting book."--Booklist, starred review
