Facebook and Skype have been working on video chat for many months now, Zuckerberg said. Facebook built it right into chat, so all your conversations start from the same place. To call your friend, just click the video call button at the top of your chat window.
Facebook will be making video chat available in over 70 different languages over the next few weeks.
Facebook's new chat design includes a sidebar that lists the people you message most. The sidebar adjusts with the size of your browser window, and it automatically appears when the window is wide enough.
Facebook is also launch a multi-person chat. Now when your friends can't figure out what movie to see, you can just add them to a chat and decide together. To include more friends in your conversation, simply select Add Friends to Chat. And just like your other chats, the history of your conversation is available in messages.
Mark Zuckerberg added that Facebook is serving over 750 million people.
Facebook is striking back at Google, which last week introduced a social networking service dubbed Google+. Gogole+ features are similar to those already available on Facebook but it also supports a videoconferencing function, which allows up to 10 people on the service to participate in a video call.
Facebook's new offering is initially limited to one-to-one video chat.
