Teens use the Internet as much, and in similar ways, as adults. But they also often engage in risky behaviour such as downloading illegal copies of movies and music. Popular social networking sites, like Facebook, can also expose teens to a variety of security risks.
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.
In this section, we examine some concerns related to online marketing.
Information privacy is an important policy and social consideration.
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. 
We don’t always hear the clock ticking when we’re online and young people are no exception. Between doing research for homework, talking with friends, updating social networking pages and playing games, it’s easy to see how kids and teens might lose track of time. Excessive Internet use, however, can negatively affect young people’s school work, health and social lives. Unfortunately, adults don’t usually discover this problem until it’s become serious.
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.
Photo manipulation, once the preserve of a small number of airbrush-equipped artists, has become commonplace in the fashion, publishing and advertising industries thanks to the introduction of photo-editing software such as Photoshop. (This program, first introduced in 1990, has become so widely used that “photoshopping” is often used as a synonym for photo manipulation.) As a result, heavily retouched photos – of men as well as women – have become nearly universal: a single issue of Vogue was found to contain 144 manipulated images, including the cover.
Digital media such as the Internet and video games have become increasingly important in the lives of children and youth. Even when young people are consuming other media, such as TV, music and movies, they are likely to be doing it through the Internet. As well, nearly all the media they consume, from TV shows to toys, have Web pages, virtual worlds, video games or other digital spinoffs associated with them.
