"Combining interactivity, rich media, and social networking, the Ceros format is perfect for delivering the personalised, engaging and measurable communications our clients need," said Euro RSCG 4D chief executive Matt Atkinson.

"Ceros was designed to provide live data and to be able to integrate with CRM and other data gathering tools," said Ceros managing director Dominic Duffy.

"Ceros proved its worth from day one," Atkinson added. "Our clients are very excited about what Ceros means both for customer retention and acquisition. Our work is proving that the unification of social, data and CRM can drive massive customer and business benefit."

The global roll-out follows successful trials by clients Diageo and Peugeot for online campaigns that took the form of interactive digital customer magazines.

Ceros commercial director Paul Fifield said: "This validates our focus on bringing value to both brands and agencies."

The value of the deal was not disclosed.
