Storyboard in conversation with Grey Group's Jim Heekin

Grey group had a fantastic 2014 - it won 20 of the 22 accounts it pitched for - including Papa Johns and Volvo and was also the top ranking WPP agency in revenue growth. It was also D&AD's most awarded agency last year - a far cry from being written off as a stuffy and irrelevant network a few years ago. CNBC-TV18 Pavni Mittal caught up with Grey's Chairman & CEO, Jim Heekin to understand what's driving creative change at Grey and how traditional agencies are competing with digital hot shops.
