The word processing glitch, commonly known as the Cupertino Effect, is named after this locality, for no other reason that some versions of Microsoft Word's English spelling checkers did not recognise the word "cooperation" and suggested "Cupertino" as its first suggestion. Overly trusting users clicking "Change All" without checking whether the spelling checker's first suggestion is the correct one, resulting in even official documents with phrases like "as well as valuable experience in international Cupertino" and "and reinforcing bilateral and multinational Cupertino and assistance actions".
