Media violence has been taken up as a public policy issue by a number of Western countries. Central to the debate has been the challenge of accommodating what may appear to be opposing principles—the protection of children from unsuitable media content and upholding the right to freedom of expression.
Music is one of the most popular and powerful forms of media that kids and teens consume: more than half of Canadian teens say they would die without it, and nearly all consider it very important to their lives. 
The video game sector is the fastest growing entertainment industry and second only to music in profitability. Global sales of video game software hit almost $17 billion U.S. in 2011. 
Pushing the boundaries for artistic expression has always been a part of popular music. However, the drive for profits may also be pushing the envelope of what is acceptable. In this section we examine some of the issues in today’s music.
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.
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.
The Internet is revolutionizing how we access and listen to music. The development of MP3s, or digital song files, has made it easy to download virtually any piece of music online.
Throughout the elementary years, parents are the main gatekeepers for their children. As such, they need to be actively involved in their children’s video game playing – selecting the games, managing how much time children spend playing, and talking to them about the values in the games they like.
For most teens, playing video games is just another recreational activity they enjoy with friends. The concern is when video game playing becomes an addictive or isolating activity.
Good-quality video games offer lots of benefits to children and teens.
