There are plenty. Hollywood has massive dominance in the international film industry as does the American music industry. The USA has spent a lot of time and money promoting its culture. It is partly a consequence of the Cold War.

But the endgoal is to produce a homogenised world culture. You can see this being pushed by groups such as FIFA and Global Citizen (the name isn't even subtle) in the last few weeks with the lead up to the World Cup, and the repeated use of platitudes like "we are one" and "unite for our future".
