DoubleFusion has signed a deal with Habbo to manage all ad inventory for the virtual world's US operations.

The ad network operator will take on responsibility for media sales and ad placement in-world. This is DoubleFusion's first large-scale foray into virtual worlds, having previously worked on a smaller program with Cyworld in South Korea.

DoubleFusion will be tasked with selling and managing inventory including billboards, branded items, sponsored rooms and other advertising and sponsorship formats available in Habbo. The ads are, according to Habbo, designed to mimic what users would expect to see in real life settings.

Habbo currently has 200 brands that advertise or run branded campaigns in its world. Those range from billboards, to deals like the two-week Spiderwick Chronicles promotion with Paramount Pictures.
