You would think so, but that's not the case. Advertising to men is more expensive than advertising to women, because more marketers are competing for those slots. I can't find any broad stats on this right now, but to use a random example, Cosmo and Maxim are both major magazines catering to otherwise similar demographics (age/income). Maxim claims 9mil readers while Cosmo claims 18mil. The cost for a four-color, full-page spread is ~230k for Maxim and ~289k for Cosmo. That's 62 readers for a dollar for Cosmo, or just 39 readers for a dollar for Maxim. [maximmediakit.com, cosmomediakit.com] If you reread the page you posted, you can see the hints of that. People talking about how older women make up a demo that "no advertiser can afford to ignore" -- that's not something an advertiser would say unprompted about 18-35 year old males, for example, because the idea of advertisers ignoring 18-35 year old males would be absurd.
