Cultural imperialism or media imperialism:

It means large cultural invades to small country which has their own culture but different form large one. The large one uses media to implant their values to the other countries. Sometimes it let people feel uncomfortable. For instance, Starbucks coffee in the Forbidden City is a kind of cultural imperialism. Next, McDonald's is cultural imperialism as well due to the fact that American hamburger isn’t the healthy food; however, they sale it to the whole world. It hits the traditional food seriously because people love this fried food even if it is not healthy.
