I haven't seen that for a while. It must have gone out fashion in marketing where I am, or the food I eat doesn't have this on their packaging. I think it is more common on non-food items. "new and improved formula".Generally such a phrase in food means they have cut costs, and UK/Irish consumers are wise to this. It is kind of cliché, I can't even remember the last time I saw it on food, it must have been post 90s but I'm drawing a blank. Maybe I'm not very observant when it comes to this, I focus more on ingredients. As it is the packaged food I eat is limited and specialised. Own-brands of supermarkets wouldn't bother with this. More likely they will silent change something, they might rename the food item. Sicilian style sausage becomes Italian style sausage, etc. They tend to use simualr style packaging so you make the transition. Though also they randomly change the packaging for no obvious reason. A lot of it has to do with positioning in supermarkets.
