A sign of shifting demand centers: the hiring of Asian "brand ambassadors" (aka, models).
In an industry with historically little diversity, even small shifts stand out.
It's like switching the bad guys in the "Red Dawn" remake from Chinese to North Koreans. Why? North Koreans don't go to movies, but Chinese do - in large numbers. So you don't want to piss off your audience.
Same thing here: after a while, the lack of Asian models is noticed in a world where the global middle class' spending shifts from mostly Caucasian to the everybody else.
