Cultural dominance is really about the media. Starting from the printing press and then really exploding once audiovisual media arrived. Of course, any sort of supremacy in other fields will also impact culture. One country is really good at science? many science papers will be written about it, in various languages. One country has a strong economy? Many theoretical science projects will be financed and become commercial - again the media will write about it and other people in other countries will copy them.
