We are a local public television organization in the US. We are a local government agency, and partner with a non-profit foundation to support our efforts. We have ads for a "Shop PBS" store, where any profit is fed back to our programming, as well as ads for fundraising drives,etc. Is this still considered non-commercial use by your definition?
Also, we are considering using Google Adsense on our site to help support our programming. Since we are a government agency and non-profit, would our use still be considered non-commercial?

If you are using AdSense that would be considered commercial (even though it's a non-profit).
