When companies want to use social media to market their brand without making it seem like they’re marketing their brand, they often turn to companies such as social application-based ad services provider RockYou.

This week RockYou announced it has raised another $50 million in venture funds, this from Softbank. The company, which distributes widgets and applications for social media, says it will use the money for brand-building, further apps development and product expansion.

RockYou has raised $118 million since its inception in 2005. Other investors are Sequoia Capital, Partech International, Lightspeed Venture Partners, DCM and SK Telecom Ventures.
