Most young children enjoy pretend play and love to imitate action heroes. But many teachers, parents and child care workers say the influence of children’s superhero TV shows or movies, can result in havoc when little fans get together.
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.
In the same way that Canadian news reporting does not reflect Canada’s multiculturalism, racial diversity ‘behind the scenes’ of news media is similarly disproportionate. In 2006, fewer than 6 per cent of CBC employees were visible minorities.  A 2000 study from the University of Laval suggests that more than 97 per cent of Canadian journalists are White. 
Sports media also contribute to the construction of masculinity in contemporary society.
In its study of masculinity and sports media, the research group Children Now found that most commercials directed to male viewers tend to air during sports programming. Women rarely appear in these commercials, and when they do, they’re generally portrayed in stereotypical ways.
Women professionals and athletes continue to be under-represented in news coverage, and are often stereotypically portrayed when they are included.
No one would deny that the mass media is big business. According to the American Motion Picture Association, Hollywood films alone pulled in $10 billion in 2011, and that doesn’t include the renting and selling of DVDs.  However, media executives argue that the economics of the industry make it impossible to avoid stereotypes of women.
Anti-Semitism is experiencing a modern revival in popular media, not only in Canada but worldwide. While Canada, with the fourth largest Jewish population in the world, is not among the nations where anti-Semitism has increased most dramatically, Prime Minister Stephen Harper has nonetheless acknowledged violence against Jewish people as a significant problem in this country . Awareness of media stereotypes and misrepresentations faced by the Jewish community is fundamental in countering this anti-Semitist resurgence with tolerance and acceptance.
Media coverage of Islam-related issues has changed dramatically since the beginning of the new millennium, both in quantity and quality. The events of September 11, 2001, thrust Islam into the global media forefront: not only did coverage of Islam drastically increase, particularly in news and entertainment media, but the way in which Islam was framed by the media changed as well.
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.
