I just found this sexist commercial for a chocolate bar that is marketed as "not for girls" via Northern Gaijin's blog:
It's obvious that the commercial will only appeal to a very small segment of population while many people of either gender will be put off the product for good. This is yet another example of how even in a fiercely capitalist society, ideology will always be more important than profit. This reminded me of a fascinating discussion in Susan Faludi's Backlash about how fashion designers in the 80ies chose to go bankrupt rather than accommodate the needs of their female customers. They disregarded a huge demand for business suits and business wear among women and kept trying to sell puffy, princessy dresses in spite of all evidence that nobody was going to buy them.
