If Hollywood only produced aprox. 6% of all films  made according the Chapman (2003), why does it dominate the global film culture?

I for one think that it had a lot to do with the setback Europe faced with war, and from then the format that the USA had produced (hybrid-genres, the hollywood studio system, americanization itself) is the reason it was able to maintain itself as the most important film producer and distributor in the world.

Hollywood dominates in the West, but there are certainly strong contenders. Whilst the revenue is lower, Bollywood produces more films per year than Hollywood, about 1000 to Hollywood's 400.

Hollywood does extremely well in the US and Europe, however outside of these areas revenue's drop significantly, out of it's $29.2 billion box office sales (as of 2009) 20.2 was in both Europe and the US.

The main reason for this is simply that English, either as a primary or secondary language is fairly common. Because of this English speaking films were always going to do well when the language is similar. 

The second reason is that Hollywood nowadays also has a much larger budget than any other cinema industry, this means that for action films or sci-fi, fantasy...anything that requires CGI or expensive props will undoubtedly look better if it's a Hollywood movie. 

Because of these two reasons, the major film releases are usually in the large cinemas, the multiplexes. It's difficult to get films in cinemas if they don't come from Hollywood or your own country / own language. Thus most cinema's will have probably 90% Hollywood films, maybe 10% of their own nations films.

Finally, Europe isn't a single nation. It's split into many many cultures with lots of different languages, it would be impossible to make a single movie industry within it, and if it had in the 20th Century it'd probably be on par with Hollywood.
