body: The NFL's copyright statement for today's big game, and presumably for other football games, contains language like "Any other use of this telecast or any pictures, descriptions, or accounts of the game without the NFL's consent is prohibited".
  
  
  How can they prohibit someone from making their own "descriptions or accounts" (or, indeed, their own pictures - if someone brings a camera phone into the audience they may be violating some stadium policy, but they're not violating copyright) under copyright law?
