Blue Orb has announced it has partnered with in-game advertising firm Double Fusion to sell and serve ads for SwitchBlade, a free cutting-edge software that brings a fully configured game controller experience to the most popular PC games, beginning with World of Warcraft. The ad-supported software is free to download and use - users can click SwitchBlade ads as they would on a website which means advertisers gain the benefits of click-throughs in a way that complements and adds value to more brand-oriented in-game placements.
