She gives an example of material that was copyrighted, the song 'Forever' by Chris Brown. When released, this song was a huge hit. One fan recorded it on her phone off the TV and uploaded it onto YouTube. However Sony Music had registered this video in their ID Content system and so gave Sony the choice of what they wanted to do next.
Most right owners, instead of blocking, will allow the copy to be published as they may benefit through the exposure, advertising and linked sales. Chris Brown's song 'Forever' received exposure 18 months after it had its day in the limelight. This was through a wedding video. The video went on to receive 40 million views. Sony allowed the upload and the song went back into the charts at number 4.
So it's important to register your videos to the ID Content system but also think carefully about policies you attach to that content as you may miss out on new audiences and new revenue streams.
