NYC ad agencies Omnicom, Interpublic to form 30bn marketing powerhouse

Omnicom is buying Interpublic Group in a stock-for-stock deal that will create the largest ad agency in the world with combined annual revenue of almost 26bn. The deal, announced on Monday, could attract regulatory scrutiny as it seeks to merge the world's third-largest ad buyer, Omnicom, with the fourth-largest – Interpublic. The names may be unfamiliar to many Americans, but some of their marketing campaigns are iconic. Those include "Got Milk" for the California Milk Processor Board, "Priceless" for Mastercard, "Because I'm Worth It" for L'Oreal and "Think Different" for Apple. The combined company will be worth more than 30bn.
