I've noticed significant differences in the advertisements directed towards women and men.
There are millions and millions of ads directed towards women telling them that they are inadequate until they buy certain products. Cosmetic advertisers must convince women that they are ugly in order to sell their goods. We're bombarded by these ads constantly, on TV, Radio, print, the web, everywhere, from birth.
On the other hand, ads directed towards men are more along the lines of how much more adequate they will be if they buy this pickup truck, SUV, tool or that gadget. There's no cosmetics industry for men, so no reason for advertisers to convince men that they are ugly, horrible beings.
In a different vein, I noticed advertising on my bananas the other day. Wow - any surface is fair game!
