I would assume the the majority of people who buy these products live in the US and Hong Kong, although apparently there are a lot of people in India, Malaysia and Singapore. The common thread here, I guess, is former British occupancy.

"Fixed do is used in Spain, Portugal, France, Italy, Belgium, Romania, Latin American countries and in French-speaking Canada as well as countries such as Bosnia and Herzegovina, Russia, Poland, Serbia, Ukraine, Bulgaria, Greece, Macedonia, Iran, Lebanon, and Israel where non-Romance languages are spoken. . . . fixed do (used in China, France, Italy, Portugal, Spain, Romania, Russia, South America and parts of North America, Japan, and Vietnam)"
Obviously there is some contradiction there...
