Search engine Ask.com partnered with Blinkx.com for video search. Ask.com will use Blinkx search technology on its search results to provide users with 12 million hours of audio and video content. Blinkx has also partnered with other search engines MSN and AOL.

Blinkx claims that it is the largest video search engine and wants to become Google for video search.

…blinkx listens to the sound track using speech-to-text technology, looks at the images on screen using advanced video analytics, and reads other information embedded into the file by using media-analysis plug-ins to extract, for example, closed captioning. In this way, blinkx is processing as much information as possible to enable both extremely accurate search, and more advanced operations such as automatic hyperlinking of related content or implicit query, which understands the content a user is producing and viewing.
