While no one has been successful in unseating YouTube as the most popular streaming video destination, several companies are now trying to steal some of YouTube's traffic by focusing on one of the video giant's weakest features -- search.

AT&T is the latest company to jump into the nascent world of video search with its new search engine, dubbed VideoCrawler.
 
While YouTube has the most traffic and most streams, users can only search material hosted on the site. With VideoCrawler, users can search more than 1,600 online video outlets, including YouTube, email the content to their friends and organize it in collections and playlists.

VideoCrawler, which is still in beta, joins a growing number of websites, including VideoSurf and CastTV, which let users search for video from multiple publishers across the web.
