I was reading that the bananas we eat today (Cavendish) weren't particularly popular until the 50s, when the more popular Gros Michel variety was virtually wiped out by a nasty disease. Apparently Gros Michel was much sweeter and had a different flavour and texture.
There are several interesting articles on the subject online, and Amazon lists a couple of books that look interesting. What I'm looking for here is primary sources - things written around the time the transition was taking place, describing people's personal reactions to the new bananas.
By personal reaction, I mean I'm not interested in sales data or whether executives thought people would like them - I want to know whether regular people noticed the change and, if so, what they said about it.
