Very interesting discussion. My favorite statement, i think by Cookie Monster, is "old is bad, and good is new". This is the not so subtle underlying mantra drummed into our heads by company advertising agencies, as they get you to buy the newest model, when there really is absolutely nothing wrong with the one you already have. I think to some extent this applies to mango crazes. That mango you have is already a good one, but the nurseries (or sometimes fellow mango snobs) try to convince you there is a better one you really need to have. Hey, it sells trees. That is why there are so many Has Been mangos. One issue not brought up is why the classic mangos remain the same for so long? One advertiser/promoter pointed out it costs millions to promote a new name, so it's cheaper and easier to stay with the old name. There is a fixed consumer name recognition that is hard to change. That is why Haden will stay on top here, Kensington Pride stays on top in Australia, Julie stays on top in Caribbean, etc. It's easier to call the new product KP1 or KP16 than to start with a whole new name and have to "re-educate" the buyer.
