According to a story on Zdnet, Facebook has managed to establish itself as a major advertising supplier because it has a unique offering to businesses that are willing to gamble a little with their marketing dollars. “Advantages include being able to target users with a precision not found in most other forms of advertising. With its quickly growing user base (800 million monthly active users and counting), the company’s social graph is exploding across all demographics, which only further fuels improved ad targeting, performance, and revenue as well.”
