The graphical UI was invented and refined here at American universities such as Stanford and MIT and by American companies, including Xerox, Apple, and Microsoft. But as history has repeatedly shown, inventing something is not necessarily synonymous with being known for it. So it may be more meaningful to acknowledge that the graphical UI paradigms and visual elements designed by Americans have become the dominant features of user interfaces on computers and smart phones throughout the world. Even the World Wide Web, invented by Tim Berners-Lee (a Brit working in Switzerland at the time), was only able to spread massively with the easy-to-use interface of the Mosaic Web browser created at the University of Illinois.
