The Media's Affect on Teenagers 2 (Artifacts 1+2)

After researching how the media affects teenagers I have found a lot information on the topic.
When researching about how the media affects teenager's self image, I found a wesite called http://www.mediafamily.org/facts/facts_mediaeffect.shtml. I read about how even children as young as fifth graders told researchers that they were unhappy with their body image after watching a music video by Britney Spears or an episode of Friends. I also read that teenagers who indentify themselves with television stars, models, or athletes, are "positively correlated with body dissatisfaction."
I found information on how the media affects teenager's and how violent they are. On http://web.aces.uiuc.edu/vista/pdf_pubs/GW12.pdf, the writer tells how on an average 18 hour day of television there are about 100 acts of violence commited each hour. Majority of teenagers today have cable and they are prone to see these acts of violence at almost any time. The website also told that the timeslots with the most violence in them is from 2-5, one of the most popular times for teens to be watching TV.
