Yea, probably, but some of it is from meddling with the formulas. I noticed it in real time when I was still a kid. Cereal would get a New Improved! label, and it wasn't always an improvement. Probably just cheaper to make. I could tell you if the OtterPops changed. They had a distinctive flavor that was different from others of the same flavor type. Perhaps a bit less sweet. They had a bit of a tart edge to them. I particularly like Louie Blu Raspberry, Sir Issac Lime, and Strawberry Short Kook :^D
