Video Search Engine - Blinkx

blinkx claims to be the world's largest and most advanced video search engine.
Fed by bots that crawl the web for audio-video content and content partnerships with over sixty leading content and media companies, blinkx uses visual analysis and speech recognition to better understand rich media content.
Users can search for content, create personal TV channels that automatically splice relevant content together and even has a feature to automatically download content to mobile devices. Blinkx is a privately-held firm, founded in early 2004 and has offices in San Francisco and London.
