CNN snatching page out of YouTube's book

CNN wants some of the clips being uploaded to popular video-sharing sites, such as YouTube, to find their way to the cable news channel.

On Monday, CNN is expected to announce the launch of CNN Exchange, a page on the company's Web site that will feature user-submitted video, audio and articles.

The pioneer in 24-hour news broadcasting is coming to user-submitted video at a time when citizen journalism has sparked much fanfare. The trend began with text--ordinary people in the blogosphere commenting about news events or in some instances, reporting breaking news stories.

The next stage in citizen journalim appears to involve lenses and viewfinders.

Video-sharing sites, such as Revver, Grouper, Guba and YouTube have become online warehouses for war footage from Lebanon, Iraq, and Chechnya.
