Selling You on Facebook

Julia Angwin & Jeremy Singer-Vine:

Many popular Facebook apps are obtaining sensitive information about users--and users' friends--so don't be surprised if details about your religious, political and even sexual preferences start popping up in unexpected places.

Not so long ago, there was a familiar product called software. It was sold in stores, in shrink-wrapped boxes. When you bought it, all that you gave away was your credit card number or a stack of bills.

Now there are "apps"--stylish, discrete chunks of software that live online or in your smartphone. To "buy" an app, all you have to do is click a button. Sometimes they cost a few dollars, but many apps are free, at least in monetary terms. You often pay in another way. Apps are gateways, and when you buy an app, there is a strong chance that you are supplying its developers with one of the most coveted commodities in today's economy: personal data.
