Frenemies: The Epic Disruption of the Ad Business (and Everything Else) by Ken Auletta - Paperback

An intimate and profound reckoning with the changes buffeting the $2 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 is the invisible fuel powering almost all media. Complain about it though we might, without it the world would be a darker place. And of all the industries wracked by change in the digital age, few have been turned on its head as dramatically as this one has. We are a long way from the days of Don Draper; as Mad Men is turned into Math Men (and women--though too few), as an instinctual art is transformed into a science, the old lions and their kingdoms are feeling real fear, however bravely they might roar.

Frenemies is essential reading, not simply because of what it says 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 marketing--revenue that is in peril in the face of technological changes and the fraying trust between the industry's key players.
