It's a positive article (as it should be) about Blinkx but the article makes no mention, even in passing, about other search resources that allow the user to search every word spoken in a video, audio feed, podcast, etc.
In fact, before Blinkx came online, Virage (now part of Autonomy and where Chandratillake used to work) was offering keyword search of audio/content and offered (and still does) it's technology on some PBS sites. We have a list of several searchable and viewable PBS programs (including the PBS NewsHour) below.
+ Nexidia, also online for a couple of years, offers phonetic searching (phoneme) search of each word spoken in a video or audio. This is unlike what's available from other sources. Others use speech recognition, keywords (surrounding the video file), closed captioning, or a combination. Nexidia is different. It breaks down the spoken word into phonemes (about 40 in most languages). This allows for faster and more precise indexing with far fewer hours of "training" a speech recognition engine to understand jargon and difficult words. It also can work with most languages.
+ Podscope's parent, TVEyes.com offers both free and fee-based services of near real-time content most national television networks and local stations in several large cities. Also, in some markets, radio search is also available. For example, in NYC you can keyword search the two all-news stations, WCBS and WINS. TVEyes has been online for more than 7 years. At one point, TVEyes also offered searchable video content from Bloomberg Business News on Yahoo Video. The TVEyes free service is accessible via the search box on their home page. More about the free service here.
+ ShadowTV,Critical Mention, and Fednet also offer near real time transcript search from both local stations and network television.
+ SteamSage, based in D.C. is now working with Comcast to develop video search tools. During the last presidential election, they offered CampaignSearch.

Recently I have found myself cooing over visualisation maps (and heat maps) of health and well being resources. The content rich data is overlayed with mapping technologies, and some interesting themes and patterns are emerging.
A lot of the talk around social media in the last year has been around information overload. Social media has provided us with new and exciting ways to create content. But it has also meant learning new ways to manage and engage with social media tools. Are we teetering on the edge of an information overload precipice?
Information overload is a figment of your imagination. Or a failure of your filter. Or a symptom of your technological submissiveness. Depends on who you ask.
What if you had to sort through 3.5 million articles and social media posts a day and try to pull out the most relevant items for your organisation? What if you then had to cobble it all together into something readable for your top groups and executives in your organisation?
