Palo Alto, California (CNN) -- Facebook announced a video-calling feature on Wednesday in partnership with Skype, the popular Internet video-chat provider.

The move comes a week after Google launched a competing social network, called Google+, which also includes a video-chatting program.

Facebook's new chat feature will show up on the site as a "call" button at the top of users' profile pages. By clicking that button or finding someone in a new "buddy list" sidebar, Facebook users can talk to each other via webcams. The company began turning that service on for millions of users on Wednesday and will add it to more accounts over time, as it commonly does for new features.

This is "the world's easiest one-click way" to chat over video, Facebook engineer Philip Su said at the news conference here. The Seattle programmer was Facebook's only full-time engineer working on development, along with Skype, a Facebook spokeswoman said.

Facebook also introduced a change to its instant-messaging service to allow people to create on-the-fly group conversations.

That move also seems to mirror a feature of Google+, Google's new social network, which is seen by some as a genuine competitor to Facebook.

this is a very interesting news because it is important to know what does facebook have of new things and if facebook has skype it would be easier to communicate with other people faster and easier saw I think that it is really good to know it.
