Facebook on Wednesday unveiled a platform that will make it easier for users to share their interests with friends on other sites across the internet.
Once signed in to Facebook, users visiting other websites can view modules displaying their friends' likes and comments about that site's content. For example, a user on Pandora, the music site, will see which artists and songs their Facebook friends like - without having to return to Facebook.
Facebook co-founder and CEO Mark Zuckerberg called the new platform, Open Graph, "the most transformative thing we've ever done for the web."
Facebook is launching Open Graph with more than 30 partners, including The New York Times, Yelp and the Internet Movie Database. CNN.com also is a partner.
The platform also will make it easier for partner sites to embed Facebook's "like" feature, which allows users to give a thumbs up to a news story, status update or other bit of digital content. Open Graph will spread the "like" button around the web, aggregating data about users' preferences outside Facebook.
