Daily, thousands of videos are uploaded on YouTube. Many of them are copyrighted.
Some of you may have wondered how YouTube treats these copyrighted contents.
The answer can be found in the following video, from TED.com, explaining how YouTube detects this sort of video and how it respects the intellectual property law.

Yesterday, another goal was reached in making YouTube a platform respectful of the copyright law. The popular video sharing website reached a deal with SIAE, the Italian Authority for artistic intellectual property. Only few details about the agreement are actually available, but what seems certain is that YouTube will pay an amount of money for the sharing of protected videos on his network.

It's actually unclear how this amount will be calculated. We'll stay tuned and report any news.
