as madam cherry says...there is not much difference, but usa english is considered to be modern and people like to use this type!

Hi Anatoliy There is no big difference; just few expressions and spelling ...

However the most popular spoken English in the world nowadays is the American English.

I prefer British English, but in truth the American style is more widespread and popular. I'd put this down to the USA's keen use of mass communication, their setting of internet standards (eg. HTML coding), widespread military presence and economic involvement in other countries.

American English is more prevalent in the world because of the much greater number of native speakers and the influence of American popular culture (movies and music). British English is considered by many to be the more "proper" form of the language however. Grammar is the same but spelling, vocabulary, accent and particularly slang are different.
