Elvis already handles digital and social activity for all of Cadbury’s brands in the UK. It beat AKQA and We Are Social to the business in 2014.
The agency will now take on work in other markets, for which We Are Social previously produced content.
Elvis has been tasked with creating "impactful content" through the "free the joy" campaign in Australia, India, Canada, South Africa, Europe and the Middle East. The account will be serviced from London.
The agency will work with Nikhil Rao, the global brand equity director at Cadbury, and maintain its relationship with Matthew Williams, Cadbury’s UK marketing chief.
Elvis recently picked up work for Lucozade, Kenco, Douwe Egberts and Tassimo.
