Mobile, search, social media
"Digital is now a fundamental part of everything we do," said Mediabrands CEO Nick Brien in a statement. "As a result of constant digital enhancements, basic human behavior continues to alter. The manner in which people interact, learn, share, and further customize information is forever influenced. The way our business operates is also being challenged and redefined. To help our clients navigate the new world with speed and sophistication, Quentin will constantly examine investments and partnerships in digital areas such as mobile, search and social platforms."
Prior to joining Universal McCann two years ago, Mr. George was chief of corporate development and managing director for Organic and headed up work for clients such as Sprint, 20th Century Fox, Mitsubishi Motors and GeekSquad.
