Mass Media!! Good or Bad idea hummm

Technology is improving and specialists are taking advantage of this resource, especially professionals in the branch of health because they can use computers plus internet as a gap to communicate populations about illness. Internet is growing at faster steps, at this point you can find internet everywhere, including remote places around the world.
Campaigns are working! For example Truth, the messages has been conscious people especially in New York City about the risk take for the simple fact of smoke. According to the article, numbers have changed the amount of smokers have decreased and the result shows the campaign is working.
In terms of the sit belts awareness, this campaign is great too with positive numbers the same as the tobacco. But, internet and media have its harmful part too; there exist a risk in terms of the negative messages send to kid’s trough television, internet, all communication media and we have little control of this matter.
Unfortunately, obesity becomes a major problem among children and that could be reflected in the fast food commercials they are seeing trough television. Lack of exercise is a problem because most part of teenagers prefers to stay in front of the television, video games and or the computers.
However, I can perceive that mass media in United States revolve marketing more than 50% because one day you see in television that grapes, for example are good for health but, few days latter they said another product is good for the same condition. So, people are changing behaviors constantly according to news everyday.
