I was watching a sketch on advertising and it hit rather close to home. The way advertisers target men and women to get them to buy their products can be very different. For women they play on our insecurities, and for men they play on reward yourself because you deserved it. Although not all adds work this way (more adds, for instance, are starting to play on men's insecurities) enough do that you can see the trend. Think about the Lynx adds (wear our deodorant and get laid), compared an add for woman's deodorant (wear our product because otherwise everyone will see those nasty white marks on your clothes and you'll know you've failed as a human being).
