"An ever-expanding array of media bombard adolescents with messages that
powerfully shape their attitudes and behavior. Growing, serious criticism has
been directed at television, music media, and video games for their emphasis
on violence as the ultimate problem solver and on unrestrained sexuality. The
undeniable power of the media could be used far more constructively in the lives
of young adolescents. Families, schools, and other pivotal institutions can help
young people become more "media literate" so they can examine media messages
more critically. They can work with media organizations in developing health-promoting
programming and media campaigns for youth. And they can support social actions
that discourage the media from glamorizing violence and sex as well as drinking, smoking,
and other drug use."
