In September 2004, Fox Sports Net became known simply as "FSN"; however the former name remained in common use until 2010, when "Fox Sports Local" was adopted for use in referencing its regional networks. 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.
