You have got to love this story on The Daily Beast which describes how Burger King took a decade (a decade!) to develop new, healthier fries called "satisfries". Thicker, crinkle cut, they have 40% less fat and 30% fewer calories. Mr Gross goes on to wax lyrical about how Burger King has used "engineering to deliver the French fry experience without all the baggage" and ends "maybe America isn't out of ideas just yet". Wow, what an innovation! Thank you America!
The author, Daniel Gross, continues that "any new product introduction carries the threat of cannibilization". That is quite interesting in the circumstances.... which are that the British have been eating this product for so long that you can buy them in the frozen food section and make them at home. (We call our french fries "chips"*, though.)
Read it and weep McCain.
* And what you call "chips" we call "crisps".
