Which products made in the United States are most likely to be successful abroad, and which are least likely?

Answer 1

"Cultural" products like movies, tv shows, video games are most likely to be successful because much of the world is still entranced by the American entertainment industry.

Commodity products (basically anything mass produced) are unlikely to be successful because there are other regions that can do it cheaper (like China) and other regions that can do it with higher quality (like Japan).

Answer 2

Most likely: Movies
Least likely: American flags
