The world’s largest online social network uses the information people share on its site, along with the apps they employ and the websites they visit, to show them ads deemed relevant to them. In the July-September quarter, Facebook reported nearly $3 billion in advertising revenue, up 64 percent from a year earlier.
Users, regulators and privacy advocates have long said that its policies are too complicated. Two years ago, Facebook settled Federal Trade Commission charges that it had exposed details about users’ lives without getting the required legal consent. Last year, an independent audit that was part of the settlement found its privacy practices were sufficient.
