Marketing, in general... a feminist issue?

In this course we have talked about how marketers tailor their ads to the demographic that shops the most. For example, the Kelly Ripa washer ad that shows her as a multi-taking mom, but is there some truth to that for marketers? Being in a marketing class as well as this course has made it clear that they do so. many. statistics. These stats show the actual percentages that influence their advertisements. See this article: http://news.cnet.com/Women-top-shoppers-online,-study-finds/2100-1017_3-241160.html. In it, Lance Rosenzweig, the CEO of PeopleSupport is quoted saying: "'Women have traditionally been responsible for 80 percent of household purchases," (http://news.cnet.com/Women-top-shoppers-online,-study-finds/2100-1017_3-241160.html). In addition, the article states that still women shop a lot: "60 percent of those who shop online are women,". My professor would say that this is obviously where we see commercials that are specific to women, because they do most of the shopping. Are these statistics drawing for the wrong examples? Should marketers be able to make their advertisements specific to women? Is this a feminist issue??
