Americanization or Americanisation (see spelling differences) is the influence of American culture and business on other countries outside the United States of America, including their media, cuisine, business practices, popular culture, technology or political techniques. Some observers have described Americanization as synonymous with progress and innovation.
Hollywood, the American film and television industry, has since the 1910s dominated most of the world's media markets. It is the chief medium by which people across the globe see American fashions, customs, scenery, and way of life.
The top 50 highest-grossing films of all time were all either made entirely or partially in the United States or were financed by US production companies, even with limited or no artistic involvement (criteria for determining a movie's country of origin are mutable and subjective but are, in practice, based on fiscal contribution and head office locations, which creates a significant advantage for a country with the money and industrial support structure - i.e. Hollywood - to fund large-scale motion pictures). Top 50 constituents set and filmed entirely in the UK, 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.
Coca-Cola, previously the top global company by revenue, is often viewed as a symbol of Americanization, giving rise to the term "Coca-Cola diplomacy" for anything emblematic of U.S. soft power. Fast food is also often viewed as being a symbol of U.S. marketing dominance. Companies such as McDonald's, Walmart, Subway, Starbucks, Burger King, Pizza Hut, Kentucky Fried Chicken and Domino's Pizza, among others, have numerous outlets around the world.
