I would lean toward there is bias in general when it comes to media. This all depends on what we believe the “media” actually is. Many websites, and some cable channels have effectively isolated their target audiences into an, “Echo Chamber.” Where only one side of the information is presented, also it is presented in a way that confirms or establishes core beliefs within one political party. A comparison between CNN and Fox News shows two very different veins of information and how they are presented. Conservative supporting media has been on a downward trend since the 1950s, with media now generally favoring a liberal bias in most publications and Internet sources. (https://web.archive.org/)
