The creators of the original Napster music-sharing site have launched a new video service allowing people to chat online using their Facebook accounts.
The service called Airtime was launched by Sean Parker and Shawn Fanning along with a host of celebrities at a New York event.
The browser-based video chat allows users to share live video without downloading any programs, by using Facebook and a webcam.
"There's something exciting about bringing spontaneity to the internet," said Parker.
"All of your interactions online are constrained by the people you already know. That wasn't always the case. If it weren't for the internet, Fanning and I would have never become friends. As we move from a social graph to an interest graph, there are great possibilities for our world. That's what we're trying to tap into with Airtime."
