Pro sports leagues and several leaders in the entertainment industry are battling over broadcasting rights with a Canadian Internet company in the U.S. District Court in Pittsburgh.

The NFL, NBA, three television networks and 10 studios — including Twentieth Century Fox, Disney and MGM — won the first round last month when U.S. District Judge Donald Ziegler issued a temporary restraining order barring iCraveTV from transmitting copyrighted shows into the United States. But iCraveTV can continue to show the programs in Canada, where the practice is legal.
