What changes happened at the Academy Awards?

This year, something happened at the Academy Awards. All the winners for best acting were from outside the United States.
    Daniel Day — Lewis and Tilda Swinton are British. He won best actor for "There Will Be Blood"; she won best supporting actress for "Michael Clayton". French actress Marion Cotillard won the Oscar for best actress for "La Vie en Rose". And Spain’s Javier Bardem won best supporting actor in "No Country for Old Men". Hollywood is increasingly looking outside America’s borders for stars and profit. Jonathan Taplin is a professor at the USC Annenberg School for Communication at the University of Southern California.  He says that today, about fifty-four percent of the ticket sales for Hollywood studios now come from outside the United States.
