This is why law suits look like government-supported coersion. This is theatre of the absurd: viacom is threatening the producer of a video that they ripped off without permission in one of their own shows. And who has the presumption of guilt now? Get the blow-by-blow in Christopher Knight’s own words and watch to the bizarre campaign ad that is at the center of this contraversy.
Update: Another good example is this video demonstrating that the NFL requires that you seeks it’s permission to talk about what you see on your TV (“”all accounts and descriptions”). The video was placed online by a law professor as an example of corporate overreach, and well, you guessed it. She received a nasty lawergram insisting that her clear fair use was actually a violation of copyright law.
