I want to know the answer to the following question:
The Two highest advertising agencies in the world located in NYC are called what?
All the background I'm provided with is that "As of 2013, the global advertising agencies of Omnicom Group and Interpublic Group, both based in Manhattan, had combined annual revenues of approximately US$21 billion, reflecting New York City's role as the top global center for the advertising industry, which is metonymously referred to as "Madison Avenue".". Is that enough to answer the question?
Answer: yes
