LONDON: Facebook has shifted its b-to-b work to Blue Rubicon after splitting with Edelman.
The win adds to Blue Rubicon's work with the social networking heavyweight, which already includes its UK corporate and public affairs accounts.
Blue Rubicon declined to comment, but it is also understood to hold the retained account for Facebook-owned photo app Instagram.
Facebook, which confirmed the hire, reported revenues of $7.87 billion in 2013. Earlier this year, it bought messaging app Whatsapp in a deal worth $19 billion.
