- the harm done to its targets, either from personal harassment or from online spaces being experienced as hostile;
- the risk that those who encounter it may be radicalized by it, becoming more sympathetic and possibly even active; and
- the effect that it has on the values and culture of the online spaces in which it happens.
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.
The internet has become a prime means of communication worldwide and this unprecedented global reach – combined with the difficulty in tracking communications – makes it an ideal tool for extremists to repackage old hatred, raise funds, and recruit members. As the internet has grown and changed, hate groups and movements have adapted, creating websites, forums and social network profiles, becoming active in spaces such as online games, and even creating parallel versions of services such as Twitter and Wikipedia.
Online hate can have an impact in three interconnected ways:
Since its earliest days, the internet has been hailed as a uniquely open marketplace of ideas, and it has become an essential means for people to access information and services. The downside of this is that, alongside its many valuable resources, the internet also offers a host of offensive materials – including hateful content – that attempt to inflame public opinion against certain groups and to turn people against one another.
It is not always easy to discern when hateful content on the internet crosses the line from being offensive to illegal. The line between hate speech and free speech is a thin one, and different countries have different levels of tolerance. The line is even thinner in digital environments where hateful comments posted lawfully in one country can be read in other countries where they may be deemed unlawful.
The Internet has revolutionized how young people watch movies: half of Canadian teens say that they download movies without paying for them at least once a week. 
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.
Advertising, particularly for fashion and cosmetics, has a powerful effect on how we see ourselves and how we think we should look. Women’s magazines in particular have a tremendous influence on body image, with researchers reporting that teenage girls rely heavily on them for information on beauty and fashion, valuing their advice nearly as highly as that of their peers.
