A new study shows the vast majority of videos uploaded to YouTube are not from major media companies, reports Reuters.
The study comes from online video tracking firm Vidmeter. It says less than 10 percent of the videos on YouTube were put there without the permission of the copyright holder. Also, those videos accounted less than six percent of the site's viewers.

Viacom, which is engaged in a lawsuit with Google over copyright infringement, takes issue with the findings, saying Vidmeter has under-counted the pirated videos because it counted only those that were taken down - and not duplicates and re-uploads.

The sample size for the research was a relatively small portion of YouTube's most-watched videos and tracked usage only between December 2006 and March 2007. Vidmeter nevertheless contends its findings are valid and show that fears of copyright infringement are overblown.
