Americanization or Americanisation (see spelling differences) is the influence of the American culture and economy on other countries outside the United States, including their media, cuisine, business practices, popular culture, technology and political techniques. Some observers have described Americanization as synonymous with progress and innovation.
The cinema of the United States has dominated most of the world's medias markets since the 1910s, and is the chief medium by which the international community sees American fashions, customs, scenery, and way of life. The majority of the top 50 highest-grossing films of all time have been made either entirely or partially in the United States or were financed by U.S. production companies, even with limited or no artistic involvement. The top 50 constituents set and filmed entirely in the United Kingdom, like some of the Harry Potter franchise, or with deliberately and quintessentially British source material, like the Lord of the Rings series, count as American productions for solely financial reasons. This coopting of the works of other nations and cultures into "American" works (and the hegemonic ability to do as such) forms part of many critical definitions of Americanization.
