Facebook’s next $10 billion business (which would be its first) takes place in the top-right quadrant. In this business, Facebook will sell ad inventory on third-party sites and target it using its own data AND third-party data.
Our source calls this business “FaceSense” because it will compete with Google’s ad network, Ad Sense. Ad Sense does about $2.5 billion in revenue per quarter; hence our source’s $10 billion figure.
