marketing demographics
A few weeks ago, I logged into Yahoo mail to see a flash ad that, in retrospect, I wish I had saved a copy of so could quote it precisely now.
T-Mobile is vigorously promoting the celebrity designer versions of the Sidekick it's now offering. This ad was in the form of a poll that read (approximately):
What is your idea of a custom ride?
- A monster SUV
- A blinged out urban lowrider
- The latest expensive European import
Since my idea of a custom ride is a convertable Mini Cooper with a diorama of action figures playing English-rules croquet glued to the hood (or possibly BRC Summer), I think we can conclude that I am not my cellphone's core target market.
