Think of three products and/or services that you see in advertisements and tell what kind of a segment you think they are targeting.
The major segmentation variables for consumer markets are geographic, demographic, psychographic, and behavioral (television, print, etc).
I will look at three products that are being advertised in the latest Time magazine.
The first is Google+. Google seems to be aiming this aid at a psychographic segment of the population. It appears to be aimed at those people who use social media because it emphasizes using this service to make sure that you only share any given post with people you want seeing that particular information.
A second is a Sprint ad for an unlimited data plan. This one seems to be aimed at a behavioral segment. It bases its appeal on things like pricing and customer satisfaction, which are things that it thinks a certain segment of the populations from cell phone plans.
Finally, there is an ad for something called SriVectin-EV. This one is aimed at a demographic segment. It touts its appeal to women who want "the return of youthful, radiant skin." Clearly, then, this ad is aimed at women who are no longer "youthful."
