**An intimate and profound reckoning with the changes buffeting the trillion global advertising and marketing business from the perspective of its most powerful players, by the bestselling author of *Googled*** Advertising and marketing touches on every corner of our lives, and the industry is the invisible fuel powering almost all media. Complain about it though we might, without it the world would be a darker place. But of all the industries wracked by change in the digital age, few have been turned on their heads as dramatically as this one. Mad Men are turning into Math Men (and womenthough too few), an instinctual art is transforming into a science, and we are a long way from the days of Don Draper. *Frenemies* is Ken Auletta’s reckoning with an industry under existential assault. He enters the rooms of the ad world’s most important players, meeting the old guard as well as new powers and power brokers, investigating their perspectives. It’s essential reading, not simply because of what it reveals about this world, but because of the potential consequences: the survival of media as we know it depends on the money generated by advertising and marketingrevenue that is in peril in the face of technological changes and the fraying trust between the industry’s key players.
