Cubics.com, the social network advertising arm of Adknowledge, purportedly now serves over 10 billion ad impressions per month across sites like Bebo, MySpace and Facebook.

Cubics enables advertisers to target their ads to a given demographic — women, 18-24 years old, from California, for example — on a social network of their choice. The company recently launched a publishers component that enables developers to advertise on their own apps.
