DirecTV (DTV)’s decision to make its “Sunday Ticket” package available to Sony Corp. (6758) PlayStation 3 users may be the first step toward giving viewers access to out- of-market NFL games on a range of Web-enabled devices, a DirecTV executive said. DirecTV, the largest U.S. satellite-television provider, announced a partnership with Sony this week that allows PlayStation 3 users to stream as many as 14 games each Sunday. For non-DirecTV subscribers, the entire season costs $339.95 a year. It’s the first time the company has made its exclusive National Football League rights available to non-subscribers on a non-mobile, television-connected device, enabling them to watch games on their high-definition TVs.
