Every single minute, 20 hours of video are uploaded to YouTube. Add to that the hundreds of TV shows now available to watch on the Internet, and the sheer volume of video posted online quickly overwhelms. How do you find the good stuff?

Blinkx, a video search company, creates some stylish order around the vast video haul. Blinkx bills itself as the world’s largest video search engine, and says it has indexed more video, audio and TV shows on the Web than anyone else–35 million hours of it. Chief Executive Suranga Chandratillake figures that’s about two-thirds of the video content online, and the other one-third is mostly locked up, requiring payment or passwords to view it.

British-born Chandratillake, 31, founded Blinkx five years ago in San Francisco after serving as chief technology officer in the U.S. for U.K. Internet search firm Autonomy. He predicted then that people would be watching more video online and would need a better way to find it.

A team from Centers for Disease Control and Prevention (CDC) also found gamers were less healthy, fatter, and more depressed than non-gamers.

Researchers from the government agency analysed data from 500 adults aged 19 to 90 in the Seattle-Tacoma area of Washington state.

More than 45% of those surveyed reported playing video games.

The team chose the Seattle-Tacoma area because its internet usage level is the highest within the US and it is one of the larger markets for media.

A UK survey from 2002, conducted by the Leisure Software Publishers Association, found the average gamer was aged between 25 and 34.

But it also suggested that the average age of the keenest players is gradually edging upwards, a finding reinforced by the CDC finding.

The team from CDC examined people’s perception of their mood, personality, health status, physical and mental health, body mass index (BMI) and quality of life.
