Razorfish is now officially a part of the Publicis Groupe, making Publicis the largest digital advertising company in the world. After acquiring the agency from Microsoft for $286.8 million in cash this summer, the deal is now complete. Razorfish will now be a part of the Publicis division VivaKi Group. The deal also puts Microsoft in a good position. As a part of the deal, the technology giant was given a 3.3% stake in Publicis and a strategic position to sell VivaKi agencies ad inventory through its ad network.
