The announcement of Omnicom Group's acquisition of Interpublic Group (IPG) may seem like a blockbuster moment in the marketing world and it is. Still, arguably, it’s more indicative of a failing model than a cause for celebration. The $13 billion all-stock deal creates the largest advertising agency by revenue, yet it also underscores the bloated, outdated nature of the traditional holding company system. Many clients are no longer looking for size—they demand agility, efficiency, results and accountability. In this light, the merger feels less like a step forward and more like a final attempt to hold on to a structure that is becoming obsolete.
