 On February 22, 2005, Fox's then-parent company, News Corporation, acquired full ownership of FSN/Fox Sports Local, following an asset trade with Cablevision Systems Corporation, in which Fox sold its interest in Madison Square Garden and the arena's NBA and NHL team tenants in exchange for acquiring sole ownership of Fox Sports Ohio and Fox Sports Florida.Cablevision simultaneously gained sole ownership of Fox Sports Chicago and Fox Sports New York, and a 50% interest in Fox Sports New England (with Comcast retaining its existing 50% stake); Fox and Cablevision, however, retained joint ownership of Fox Sports Bay Area.Fox Sports Chicago ceased operations in June 2006, after losing the regional cable television rights to local professional teams (including the Chicago Bulls, Blackhawks, Cubs and White Sox) two years earlier to the newly launched Comcast SportsNet Chicago.
