and advertising sales between SportsChannel and Liberty's Prime Network regional sports group. Through this partnership, the two companies formed the sports news service NewSport, replacing SportsChannel America. On April 25, 1995, NBC sold its 50% interest in SportsChannel New York to Rainbow Media for US$93 million; NBC cited that "owning a piece of SportsChannel New York made less sense" after Cablevision and ITT purchased competing regional sports network, MSG Network. NBC retained its ownership in the other networks. On June 30, 1997, Fox/Liberty Networks, a joint venture between News Corporation and Liberty Media, purchased a 40% interest in Rainbow's sports properties including the SportsChannel networks, Madison Square Garden, the New York Knicks and the New York Rangers. Through the deal, the SportsChannel networks would be integrated into Fox Sports Net, a group of regional sports networks launched in November 1996 through News Corporation's purchase of Liberty's Prime Network group; SportsChannel New York would also be rebranded as Fox Sports New York, with Cablevision-owned MSG also becoming a separately branded FSN outlet. Weeks after deal was announced SportsChannel would discontinue its national programming in favor of Fox's programming and discontinued NewSport, replacing it with American Sports Classics, a network focusing on replays of past sporting events and historical sports documentaries. National Sports Partners, the venture formed through Cablevision's entry into the News Corporation/Liberty partnership to operate the existing and newly acquired owned-and-operated regional networks, later announced that it would relaunch the other SportsChannel networks under the "Fox Sports Net" banner. SportsChannel New York was the first to rebrand, as Fox Sports New York, on January 27, 1998. Five of the seven other remaining SportsChannel networks relaunched as member networks of Fox Sports Net later that week. Two of the SportsChannel networks would not become part of FSN, one of them not immediately. After Comcast acquired a majority stake in Philadelphia-based entertainment company Spectacor to form Comcast Spectacor in 1996 and announced plans to create its own regional sports network, Rainbow Media decided to shut down SportsChannel Philadelphia and sister premium service PRISM on October 1, 1997, with both networks' NBA and NHL contracts with the Philadelphia 76ers and Flyers being acquired by the new Comcast SportsNet Philadelphia (which replaced SportsChannel Philadelphia on local cable systems). SportsChannel Florida was also unable to join Fox Sports Net at the same time as its sisters as Wayne Huizenga, owner of the NHL's Florida Panthers,
