Most of YouTube’s revenue is owned by video copyright owners. In 2010, it was reported that almost a third of commercials were uploaded without permission from copyright owners. YouTube offers copyright owners the opportunity to find and delete their videos or continue to advertise income. In May 2013, Nintendo began to impose its ownership of the copyright and announced the advertising revenue of the creators of the videos in which screenshots of their games were published. In February 2015, Nintendo agreed to share the proceeds with the video creators.
