Google bars data from Facebook as rivalry heats up

Google will no longer let other services automatically import its users' email contact data for their own purposes, unless the information flows both ways. It accused Facebook in particular of siphoning up Google contact data, without allowing for the automatic import and export of Facebook users' information.

Facebook, with more than 500 million users, relies on email services such as Google's Gmail to help new users find friends already on the network. When a person joins, they are asked to import their Gmail contact list into the social network service. Facebook then tells the user which email contacts are also on the social network.

In a statement, Google said websites such as Facebook "leave users in a data dead end." Facebook did not immediately provide a comment on Friday.

While Google framed the move as an attempt to protect its users' ability to retain control of their personal data on the Internet, analysts said the move underscored the battle between Google, the world's largest search engine, and Facebook, the dominant Internet social network.

"The fundamental power dynamic on the Web today is this emerging conflict between Facebook and Google," said Gartner analyst Ray Valdes. "Google needs to evolve to become a big player in the social Web and it hasn't been able to do that."

"If people do search within Facebook, if they do email within Facebook, if they do instant messaging within Facebook, all of these will chip away at Google's properties."

RECIPROCITY

Google said that while it makes it easy for other Web services to automatically import a user's contact data, Facebook was not reciprocating.

"We have decided to change our approach slightly to reflect the fact that users often aren't aware that once they have imported their contacts into sites like Facebook, they are effectively trapped," Google said in an emailed statement.

"We will no longer allow websites to automate the import of users' Google Contacts (via our API) unless they allow similar export to other sites," Google said.

Some technology blogs were reporting that Facebook still appeared to be allowing users to import their Google Gmail contacts into Facebook as of mid-day Friday.

A Google spokesman told Reuters that the company had begun enforcing the new rules "gradually."

Google also stressed that users will still be able to manually download their contacts to their computers in "an open, machine-readable format" which can then be imported into any Web service.

Google has coveted the wealth of information that Facebook's half-billion users generate and amass. Having access to that data could be especially valuable to Google, whose business model is based on allowing its users to find any information anywhere on the Web.
