About Rhythmone, LLC

If you film it, blinkx will show it. The company operates a video search engine that crawls the Web for video. (blinkx differs from video sharing site YouTube in that it doesn't provide a place to host video.) The service boasts about 35 million hours of indexed video from more than 720 partners and serves ads against them. The technology behind blinkx uses speech recognition to analyze and process the video itself, instead of relying solely on text keywords as a search criteria. It powers the video searches for Ask.comLookSmart, and hundreds of other sites. The firm was launched in 2004 by Suranga Chandratillake, former CTO of Autonomy Corporation. It completed an IPO on the London Stock Exchange in 2007.

The company makes its money by delivering video content and advertising. Its AdHoc technology and advertising platform displays advertisements based on a user's search keywords. Companies who advertise on blinkx's platform include Disney, IBM, JP Morgan, and Procter & Gamble.  

Besides searching for specific videos, users can create personalized video playlists and build a customized "video wall" for their own Web pages. blinkx also has a default setting called Safe Search that blocks adult content. Another of its dozen or so products is blinkx Remote, a Web search tool that finds free, full-length TV shows.   

blinkx was originally spun off from Autonomy. Both companies used the University of Cambridge for research and development (their executives are alumni of the school). blinkx's technology has secured more than 110 patents.

The company has headquarters offices in Cambridge, UK and San Francisco. It has additional locations in Boston, Chicago, London, Los Angeles, Montreal, New York, Seattle, and Tempe, Arizona.

Revenues for fiscal year 2012 increased by 73% to $114.4 million, up from $66.1 million in 2011. It cites growth in the online video advertising market as a reason for the jump. Profit for the year was at $3.9 million, compared with $7.6 million for 2011. Causes for the drop include acquisition and integration costs, and amortization on purchased intangibles.

In 2011 blinkx expanded with the acquisition of online ad company Burst Media for $30 million in a mix of cash and stock. It made the purchase to help build personalized online TV channels, which it hopes will attract more advertisers. As a result of the transaction,  Burst serves blinkx's roster of videos through Burst's network of publisher websites. The deal gave blinkx access to Burst's audience of more than 130 million unique users.

Also that year the company acquired New York-based search marketing firm Prime Visibility Media Group (PVMG) for $36 million. The deal is designed to support blinkx's ability to deliver videos in search results. PVMG's network claims an average of 600 publishers and 350 publishers, and receives about 1.5 billion text search queries per day.
