Facebook is the social world behemoth. They are beyond popular with a significant fraction of the industrialized world's population in their databases.
The thing that makes Facebook an advertising powerhouse is that their users tell them all kinds of details about their demographics and personal preferences. That means that advertisers can get ultra-targeted audiences for their messages.
It is possible to narrow down your target by sex, age, marital status, neighborhood plus many preferences as indicated by the pages people "like." Of the approximately 1.5 million Bay Area Facebook users you can narrow that down to a select group of just a few thousand people.
