The Internet provides marketers with many opportunities to elicit personal information from children. Kids love playing on the Web, and commercial sites for children are continually ranked as top online destinations.
Images of men and women in the media are often based on stereotypical roles of males and females in our society. Because stereotyping can affect how children feel about themselves and how they relate to others, it’s important that they learn to recognize and understand gender stereotypes in different media.
Many preschoolers are already active computer users. According to a 2012 Ofcom report, one-third of children ages 3-4 access the Internet using a computer, while a 2011 survey by Common Sense Media found that roughly the same number have used mobile devices such as smartphones and tablets. While children at this age have a limited attention span for online activities, Internet images and sounds can stimulate their imaginations and add to their experiences.
There’s significant evidence that media education can counter unrealistic media representations of men’s and women’s bodies. For example, a 2010 study found that showing the video Evolution (which was created by Dove to show how media images of women are manipulated) significantly reduced negative effects on confidence and body satisfaction of young girls when they looked at pictures of ultra-thin models afterwards.
At the end of the day very little that can be done to prevent kids from encountering online advertising. The best approach is to teach them, from an early age, the purpose of advergames, branded characters and commercial websites.
In this section, we examine some concerns related to online marketing.
Music is a significant medium in a young person’s life, particularly during the teenage years. While other media may occupy a greater number of hours, it is most often from music that teenagers define their identities and draw cues about how to dress and to behave.
Despite the popularity of the Internet, movies and TV still dominate young people’s media use (though they are increasingly watching both online).  Given this widespread appeal, these media may have an indirect effect by influencing how groups or cultures view body image.
Traditionally, most of the concerns about media and body image have revolved around girls, but more and more, researchers and health professionals are turning their attention to boys as well. A growing body of research indicates that although boys are less likely to talk about their insecurities, they too experience anxiety about their bodies.
