YouTube has been been paying a percentage of ad revenue to a small percentage of top video producers. Now they've opened their YouTube Partners program and the revenue that comes with it to just about everyone.
To become a YouTube Partner, you need to enable your excisting or new YouTube account. You must also control the rights for the video and music that you post. The YouTube faq reads:
"For your videos to be eligible for monetization, you must own all the necessary rights to commercially use all visuals and audio, whether they belong to you or a third party. By commercial use rights, we mean the rights to make money from the video."
The YouTube Partner program is now available to all in Argentina, Australia, Brazil, Canada, Colombia, Czech Republic, France, Germany, Ireland, Israel, Japan, Mexico, Netherlands, New Zealand, Poland, South Africa, Spain, Sweden, United Kingdom and the United States.
