The role of the news media is ostensibly to inform. In order to do this, however, the media must present information in a relatively unbiased way. If citizens obtain information about the world primarily through the media, and the media presents this information through a biased lens, the public acquires an analogous bias. So how successful is the media in presenting an unbiased perspective?
