The movies won't affect your printed maps, or maps you see in serious contexts (like in classroom, or in a BBC article). But I'm willing to bet that in your day-to-day experience, you see a roughly equivalent number of maps in movies and videogames. Which, unless you have non-average watching habits, will most likely be US-made.

I probably do see a fair number of those maps, but the context matters. Such maps are usually in the background and not what I'm paying attention to. If I'm actively using a map then it's a UK centered one 99% of the time.

True. And I inferred the context is about seeing maps in general - which includes movies, games, advertisements, company logos, computer icons, etc. I.e. the situations in which you see depictions of the world (and mentally recognize them as such), not necessarily use them to find your way.
