On the other hand a lot of candy gets bigger and bigger. I am pretty sure the candy bars and ice cream scoops I got when I was a kid were half of the current size. Or even less.
I love to watch the shrinkage of ice cream. Over the past 10 years, the standard packaging of ice cream has gone from 1/2 gallon (1.9 L) to where they are currently at 1.4 L, with prices staying relatively the same.
There’s also the trend toward “whipped” ice cream which has fewer calories and lower COGS because it is mixed with air.
