Apparently, the 'create-your-own-Barbie-doll' section acts as a
sort of a pretty ingenious marketing research tool for
Mattel.
I guess it's pretty true when I tried it out myself. This section
can tell Mattel a lot of information such as the current fashion
trends, consumer preferences, consumer demographics and so on....
all while trying to reach out to them by letting them have fun
designing their own Barbie dolls online.
Oh well... time to get back to tackling my tutorials.
