Google doesn't sell an indexed list of users and their interests: you can't buy the data and then use it how you want. But, yes, pimping it out was just hyperbole for renting it for particular, well-defined purposes.

They can specify the market demographics desired and google or any other ad network delivers the matching eyeballs.
