Knowledge is hidden around us. All you need do is scratch the surface to learn something cool.
For example, most people know that Persian rugs don't come from Persia -- since "Persia" doesn't exist any more. Persia is an old name for what is now Iran. Sellers believe consumers are less likely to buy rugs from "Iran" than fanciful Persia.
Shopping for cinnamon I just learned there are many countries that produce the spice: e.g., China, Vietnam, et al. Highest quality cinnamon is labeled "Ceylon cinnamon". Again, this identification is fictitious and designed purely for marketing. There is no country named Ceylon today. So where did the name come from?
The republic of Sri Lanka was formed in 1972. Before then, from 1948 to 1972 the place was called Ceylon. Premium cinnamon sold today as "Ceylon cinnamon" is actually from Sri Lanka. Sellers count on you reacting more positively to "Ceylon" than the true country of origin.
Similarly, cinnamon from Vietnam is now marketed as "Saigon cinnamon" to steer away from the name of a country we famously fought a war against. "Saigon", a former city in Vietnam, is no longer called that: its real name since 1976 is "Ho Chi Minh City". Can you guess why sellers didn't choose that for their product? :)
