Should we now call it Facecrook? Seen on Mashable:
According to a Bloomberg report Wednesday, a new service called Facebook Exchange will allow advertisers to target users based on their browsing history.
Your computer already remembers your history via cookies, enabled on many websites. Now, if that site is linked to Facebook (if it has a Like button anywhere on the page, it is linked), it will share information from that cookie the next time you log in to the social network.
After that, the Facebook ads you see may be based on that cookie. So if you’re in the market for a car and peruse car reviews online, your computer will remember and tell Facebook. This will increase the likelihood that you’ll see ads for cars.
