advertising holding company that invests in agency partners in the areas of advertising, marketing, media management, technology, analytics and consumer insights, direct marketing, and strategic consulting. The company is headquartered in New York City and also operates a corporate office in Toronto, where it was founded. It earned approximately US$1.33 billion in revenue 2015. MDC typically invests in creative and digital firms. Historically, it invested in agencies during times when similar companies have scaled back on acquisitions. While the company has mainly invested in North American small to mid-sized agencies, it extended onto new global markets in the 2010s. As of 2015, 9% of the company’s revenue came from outside North America. MDC does not generally acquire agencies outright, but instead partners with agency management by acquiring a 51 to 80 percent initial stake. Instead of integrating the firms, acquired agencies continue to manage their own day-to-day operations. MDC provides support to the agencies in which it has invested including business strategy and financial resources. It operates a Strategic Resources Group, which supports the development of partner agencies. In 2004, Adweek called the company an "anti-holding company".
