The Associated Press reports that a Utah judge has blocked Aereo from operating in some Western states until the U.S. Supreme Court takes up on April 22 a case over whether the Internet streaming service violates broadcasters' copyrights. The district judge said that Aereo's retransmission of signals is indistinguishable from what cable companies do, and letting Aereo stay in business would "damage broadcasters’ ability to negotiate with legitimate licensees, siphon viewers away from their websites and subject them to potential piracy," the AP also reports.
