The Fox Entertainment Group is an American entertainment company that operates through four segments, mainly filmed entertainment, television stations, television broadcast networks, and cable network programming.

 The transaction was completed on March 12, 2005.

 In 2015, 21st Century Fox, producer of "The Simpsons", began selling licensed Duff beer in Chile, with a view to driving out unlicensed brandjacking.
