But even in countries where Cadbury chocolate is made by Cadburies, it’s not all the same. Australian Cadbury chocolate has always been made to a higher melting temperature than English Cadburies. So that (even without a thin sugar shell), it melts in your mouth, not in your hand.
This probably doesn’t count, but I ran tons of Bell & Howell 16 mm projectors in the 1970s. (They were very nice projectors for their price class.) In the 1990s, I did a lot of work for Bell & Howell when they made mailing and postal equipment. Now I’m watching advertisements for Bell+Howell TacPens, sunglasses, and some plastic thing that helps you get somebody up and out of their chair.
Burger King was one of the divestitures I worked on during my career (one that didn’t go through, Pillsbury and Pepsi were in continual talks to sell Burger King to Pepsi while I worked for Grand Met/Pillsbury. Pepsi at that time owned Pizza Hut and a bunch of other restaurants - you could tell where the talks were on if Burger King carried Coke or Pepsi on its menu). It had always been a complicated mess of trademarks (at least in the 1980s when I worked on it)…because “Burger King” is such an obvious name for a fast food burger restaurant that country by country, state by state, and sometimes location by location, the trade name has had to be acquired. Given the variations in international law, the willingness of current name holders to sell, etc., it was a nightmare.
