Random people from all these countries can name of the top of their head a bunch of any of the following:

- US presidents

- US pop artists

- US filmmakers

- US cities

- US CEOs

- US companies

- US TV shows

I stopped there but I could go on for long. Now, take any country X other than the US and ask a random resident of any of the other countries to name just one of each category: a president of X, a CEO, a film, etc... If you think the answer has any chance to compete with the equivalent question asked of the US, well, I think you don't realize how big the cultural influence of the US is. What is domestic news in the US is still news in the rest of the world, but the reverse is simply not true.
