Warner Music has agreed to make its library of music videos available to YouTube, marking the first time that an established record company has agreed to make its content library available to the user-generated media company.
Under the agreement, YouTube users will have full access to videos from Warner artists. They will also be permitted incorporate material from those videos into their own clips, which are then uploaded to YouTube. Warner and YouTube will share advertising revenue sold in connection with the video content.
