The Problem with Webcasting provides a nice overview of the new webcaster’s (copy) right that is being pushed by the U.S. WIPO delegation.
There’s a new restriction on content waiting in the wings–a “webcaster’s right” that allows websites to control the dissemination of content they put up. With this new privilege, they’ll be able to prevent retransmission even if the copyright on that content is owned by somebody else–even, in fact, if that content was in the public domain.
