driven by society?

there are so many variations of the mooncake nowadays. they come in all sorts of flavours, shapes and sizes! there's yam, durian, almond, chocolate, strawberry and what have you.. i wonder if the little children nowadays even know which are the traditional ones. but then again, you can't blame the hotels, restaurants and bakeries for coming up with all sorts of flavours. at the end of the day, each of them just wants to have the lion's share of the market.
