Question:

In a host of emerging markets (e.g., India, Brazil, Thailand), 50+ percent of the population is under 25 years old. One marketer observes: ‘‘teenagers are teenagers everywhere and they tend to emulate U.S. teenagers’’ (Advertising Age International, October 17, 1994). Is there a global teenager segment? Do teenagers in, say, Beijing really tend to emulate L.A. teenagers? Discuss.
