The YouTube Live web cast is scheduled on November 22 and Silicon Alley Insider says there's been speculation that they will announce their own web casting service similar to Ustream, Stickam, Justin.tv, and Mogulus at the event. Nicholas Carson spoke to a YouTube company source who has seen mock ups of the user interface and said, "Of course something could go wrong and they might not launch it," and a YouTube spokesperson contradicted the claim saying, "We're working with a third party to live-stream our event called Live. We have no product to announce at this time." YouTube Live - 11/22/08 From: Live Description: YouTube Live! is, first and foremost, a celebration of the site's vast user communities; everyone from bedroom vloggers to world-famous rock stars, musicians, comedians, athletes, artists and more. Part concert, part variety show and part party, the event will bring to life many of the amazing videos and talent that YouTube viewers have already made popular on the site. The two-hour event will take place on November 22, 2008, in front of a live audience in San Francisco; an audience of millions will be able to experience a simultaneous live stream on the site." MG Siegler says that VentureBeat has confirmed through an anonymous tipster that the third party is Ustream and he noted, "More interesting is the rumor that YouTube could use the event to launch a live-streaming service of its own. If that is true, it seems unlikely that YouTube would go to all the trouble of partnering with Ustream for the event if it’s just going to launch a product that directly competes Ustream at the event." Siegler also thought that perhaps YouTube might announce a formal partnership with Ustream to handle the live streaming on YouTube. This may give some credence to what Steve Chen told Sarah Austin earlier in the year that YouTube was interested in getting into live streaming and that they hoped to launch something this year.
