Typos have been with us ever since Guttenberg invented the printing press in 1440.  One famous example is the so-called “Wicked Bible” from 1631 which mistakenly says “Thou Shall Commit Adultery.”  Only about 1,000 copies of the Wicked Bible were printed before they were recalled.  Now, they are very expensive collectors’ items. here’s a pic:

In modern times, auto-correct creates it’s own issues , one being the so-called “Cupertino Effect.”  The Cupertino effect  is what happens when a spell checker suggests or auto-corrects a correctly spelled word with an unintended word.  The Cupertino effect got its name because Word ‘97 suggested Cupertino when co-operation was spelled without a hyphen. Cupertino is a city in California, most famously the home of Apple. Here’s an example: “Co-ordination with the World Bank Transport and Trade Facilitation Programme for South East Europe will be particularly important in the area of trade facilitation and shall be conducted through regular review mechanisms and direct Cupertino.”

Other common words that result in a “Cupertino”:

• Cooperation correcting to copulation
• Highfalutin correcting to high flatulent
• Socialite correcting to socialist
• Prosciutto correcting to prostitute
