why American's culture is called pop culture

I think the basic reason is that the most Americans are popular.Such as music,like hip-hops,jazz,they dates back at an early age from the U.S. What's more, American is a nation that is capable to accept other's opinion, ideas, so it is a nation which changes at a high rate of speed.
