Nintendo has announced a new set of guidelines regarding use of their copyrighted content (videos, screenshots) online.
The guidelines state that Nintendo will not claim copyright infringement against videos and screenshots captured from games they own copyright for uploaded to the internet, and allow monetisation through the systems available on platforms listed, including Youtube and Twitch. There are several restrictions, however: For example, footage from games that have not yet been released or pirated software, are not allowed.
