AMC Networks
AMC Networks Inc. is an American entertainment company headquartered in 11 Penn Plaza, New York, that owns and operates the cable channels AMC (its eponymous brand), IFC, WE tv, BBC America (through a joint venture with BBC Studios), and SundanceTV; the art house movie theater IFC Center in New York City; the independent film company IFC Films; and premium streaming services Sundance Now and Shudder. In addition, the company operates AMC Networks International, its global division.
Fox Corporation
Because Disney owns the American Broadcasting Company (ABC), and 21st Century Fox owns the Fox Broadcasting Company, a full acquisition of Fox by Disney would be illegal under the Federal Communications Commission (FCC)'s rules prohibiting a merger between any of the four major broadcast networks.
