Er....I just remember the ring pulls being changed to catch up with the ones that the USA had waaaay before we did. Which are more user-friendly. Don't remember any "Green" campaigns to introduce them in the UK. Mind you, I went to school with americans. Before I knew it marathons became snickers, we were all eating jolly ranchers, baby ruths & reese's peanut butter cups instead of our usual (but boring, scottish) soor plooms, sherbert lemons. Then we got Pop Tarts, Cheerios, Mountain Dew and the rest, as they say, is history.
