NEW YORK (AP) - Quick on the heels of Google's launch of its latest social-networking venture, Facebook is rolling out video calls. It's powered by Internet phone company Skype.

Facebook said Wednesday that it is also rolling out a group chat feature. Facebook users can now create instant group chats if they want to quickly message a small group of their friends.

CEO Mark Zuckerberg says Facebook now has 750 million users. And they share 4 billion things such as photos, links and status updates on the site every day.

Google Inc. opened up Google Plus last week on an invite-only basis.
