I also don't think it's a new market. It's not about advertising or not advertising. It's how you advertise. Shout out "great" and "unbelievable" and "gorgeous" more often than other people would breathe in the same time... Or just be more laid back, show you're self-confident and are not so desperate as to beg for people's attention.
Or maybe it's just one of these cultural things; I admit I've long given up trying to understand Americans.
