Research on Media Power.

I believe that media have a stranglehold power on public opinion. Through my research I want to know how media can shape the public; consequently controls the world. Most people, for example, believe every thing they see on news TV. I don't think that news is showing the whole face of truth because it can be biased. Then masses might be influenced by misleading news which, normally, not for the public benefits but minorities desires. News media could influence on our choices to select decision makers. Hence, in what way we can eliminate the supremacy that media impose on audience.
