The game was the fourth overall telecast to be streamed live online legally in the U.S. both to computers (via NFL.com and NBCSports.com) for the second time and mobile devices (via Verizon Wireless's NFL Mobile app). The game marked Al Michaels ninth time conducting play-by-play for a Super Bowl (Michaels had previously done play-by-play for Super Bowls XXII, XXV, XXIX, XXXIV, XXXVII and XL for ABC and XLIII and XLVI for NBC). For the game live-streamed on Yahoo in 2015, all silver "CBS" marks in the graphics package were replaced by purple "Yahoo" logos. The game used the top-screen version of the scoring banner. The 2015 schedule was released on April 21, 2015. The defending Super Bowl champions the New England Patriots faced the Pittsburgh Steelers during the NFL Kickoff Game on Thursday, September 10, 2015. Other notable games included the Seattle Seahawks versus the Green Bay Packers (Week 2) and the New England Patriots versus the Indianapolis Colts (Week 6) in a rematch of their respective conference championship games. It also placed a Sunday night game (Green Bay Packers at Denver Broncos) against a World Series game for the sixth straight year. The final Sunday night game of the season – January 3, 2016 – likewise was a flex game; the slot was left vacant when the schedule came out as has been the practice over the past seven seasons. The game's teams (and by extension, its location) was announced after most Week 16 games. It was filled by the Minnesota Vikings at Green Bay Packers. The Arizona Cardinals wound up playing on consecutive Sunday nights — at the Seattle Seahawks in Week 10 and then, at home against the Cincinnati Bengals in Week 11 (Cardinals won both of those games), with the latter being flexed into the Sunday night slot. In November 2015, "The Hollywood Reporter" reported that in response to the success of the package under CBS, the NFL was planning to negotiate a long-term contract for "Thursday Night Football", with CBS, Fox, NBC, and Turner Sports showing interest. The "New York Post" reported that this deal would also include the sale of a stake in NFL Network itself. On December 16, 2015, it was reported that the NFL was shopping the "Thursday Night Football" package as a one-year deal with an option for a second year, similarly to the current arrangement with CBS; the league also requested that bidders outline goals for "growing" NFL Network.
