The new
coke was the result of the
coca-cola company performing
taste tests and finding that their
sweeter test product scored better. This was because in the amounts and time period that they gave their
test subjects, they did actually prefer the new coke. When the product was released coca-cola soon discovered that when consumed under every day living conditions their new product was an
abysmal failure. They soon reintroduced the old coke as "
coca-cola classic".
As for the addictive substances variety of coke, the "new coke" seems to be Everquest.
