Actually, here in good 'ol socialist Sweden all of our groceries, with a few exceptions, used to look like that up until the end of the 90s. I remember as a kid eating cereals from a big white box with the word "CORNFLAKES" on it in big blue bold letters.
Umm, no they didn't. What you're talking about was a particular brand, Blåvitt[1], owned by the Konsum chain of stores. It was a very concious (and successful) marketing strategy, and not some generic non-brand.
