My guess it's safe to say when any smaller company that created a niche based on a superior taste/quality/texture is purchased by one of the big guys....it's going to change.
The Mars bars mentioned upthread....boy, have they changed. Once a week or so, my mom and I would take a trip into our tiny little town and stop and get a candy bar. We lived in the country, about two miles from town and town consisted of one tiny little grocer. Our regular shopping was done about ten miles away in the next larger town.
We'd drive into town and go to Eddie's. Not sure what Eddie called the store, come to think of it, but the owner's name was Eddie, so we all called it Eddie's. We'd each carefully choose our favorite. Mostly we both chose a Mars Bar. Eight delicious almonds, evenly spaced, two by two atop that delicious nougat enrobed in chocolate. What's not to love? As a teen, suddenly there were just a couple of scattered almonds on top. By my twenties, almond pieces in the nougat, if I remember correctly. I haven't had one since, so who knows what they taste like now...
In the summer, I'd get to ride my bike to town, along with some other kids. We'd take our dimes and get a blue Mr Freeze and eat it while riding the bikes home, blue raspberry flavor dripping down our chins an on our hands. Wonder what they taste like these days? I don't think I want to know.
