- web uploads
Copyright is often a prickly issue, as many of the uploads are copyrighted material with some commercial value, typically (though not always) uploaded without permission from the copyright holder. Many copyright holders are increasingly patrolling video-sharing sites looking for their material, and typically will issue "take-down" orders for any material they believe to be excessive. (There is some controversy over whether some of these take-down orders are themselves ethical, such as videos of official presidential debates which arguably ought to be available to everyone.)
The relationship between video-sharing sites and copyright holders has become increasingly complex.
