The surest example of this is to move to another country. You expect adjustment for language and dress and such, but nobody tells you about the culture shock of the grocery store. Even between US and Canada, grocery stores look completely different. You don’t recognize any of the branding and you feel totally lost as to what to buy. You can’t find the butter that you like and milk is in different containers, etc. All the cookies and chips are different brands, or if they are the same, the packaging is different so you don’t recognize it. Basic things like this that really make you feel like an alien.
What’s curious to me about rebranding debacles like this one is that companies don’t go into this sort of thing lightly. They focus test and market research the hell out of a change like this. That mistakes on this scale still happen is really interesting. Sometimes all the focus groups tell you something is better, but then the public rejects it. Rather like the polls and pundits being wrong about an election outcome.
