On June 30, 1997, the Fox/Liberty joint venture purchased a 40% interest in Cablevision's sports properties including the SportsChannel America networks, Madison Square Garden, and the New York Knicks and New York Rangers professional sports franchises, a deal worth $850 million; the deal formed the venture National Sports Partners to run the owned-and-operated regional networks. In early 1998, SportsChannel America was integrated into the Fox Sports Net family of networks; SportsChannel Florida, however, remained as the lone SportsChannel America-branded network before it joined FSN as well in 2000 after News Corporation and Cablevision purchased Florida Panthers owner Wayne Huizenga's controlling interest in that network.
