"We're delighted to be continuing our long and successful relationship with the Volkswagen Group for the next three years. Working together for more than 15 years has enabled our experts to truly understand the needs and ambitions of all five brands as well as the mindset of potential purchasers. In the next three years, we'll be working hard to take that even further and understand how purchase decisions change and evolve as the media landscape continues to develop," said Stephen Allan, Worldwide Chairman and CEO of MediaCom.
