Take that Viacom!
According to a spokesperson, YouTube is set to launch a mobile version of the popular video-sharing website in May 2007 for European users. The service will launch a month later for U.S. users as a result of the company’s exclusivity clause on a mobile video deal with Verizon Wireless.
In response to my question if YouTube is developing a mobile client, the spokesperson said that the company had been talking about it, but had no information to share at this time. Check out a preview of the blocked mobile site or this demo site: http://m.youtube.com/?client=ytdemo which you can see from some mobile phones (let us know if your phone can access it).
