How does media research Impact media literacy?

Media Research has had a huge impact on media literacy in a large number of ways. Public Opinion Sampling is one of the largest ways which research can have a large impact. Using public opinion has had impact on our society's public life, and in public policy and decision making. This is true when looking at events such as opinion poles in elections for officials. When you see the poles on who has more votes, some people are swayed to certain way. Measuring audience size also has an impact on media literacy. Advertisers used to lie when they showed the amount of people that followed whatever newspaper, radio station or television show they were working with. This would influence people to watch, read, or listen wrongly and the impact of actually measuring has brought truth to the media and to the media's audience.
