Social networking company Facebook has teamed up with Internet phone service Skype to offer free video calls to users.

Last week, Facebook founder and CEO Mark Zuckerberg had revealed that the social networking site will "launch something awesome."

Zuckerberg had said that the project had been developed at the 40-person Seattle office.

Google+, Google’s latest social networking service that was launched recently, is said to be drawing users with its group videoconferencing function. Zuckerberg is said to be the most popular member of this service by Google.

Though the video chat function by Facebook involves only two people, the company has said that it would add a group chat option in the future.

Zuckerberg said the video chat service is awesome.

He said, "We think this is awesome because we’re using the best technology that’s out there for doing video chat with the best social infrastructure that’s out there to create some really cool new scenarios."

Facebook also said the number of users of the social networking site has grown to 750 million. Last month there were reports that the user numbers of the site were dwindling, which the Facebook was quick to refute.
