First I will approach the political with a broad sword rather than a scalpel.
That I believe is one of the most difficult questions to answer because the actions taken by media tend to be subtle in the mainstream - not so subtle in the alternative outlets however. Each company has it’s own political agenda and this would include media companies.
A snippet from Wikipedia: Media bias in the United States occurs when the US media systematically skews reporting in a way that crosses standards of professional journalism. Claims of media bias in the United States include claims of liberal bias, conservative bias, mainstream bias, and corporate bias. A variety of watchdog groups combat this by fact-checking both biased reporting and unfounded claims of bias. A variety of scholarly disciplines study media bias.
This leaves us at the mercy of the watchdog groups which usually have their own agenda and bias. Before rolling out an improvement to a framework, we need to comprehend that people are inclined to accomplish an option rather than nothing. “Intervention Bias makes us likely to introduce changes that aren’t necessary in order to feel in control of a situation”. The situation to be controlled is the neutrality of the bias. Either way somebody wins because no-one is perfect.
Unfortunately science is embroiled in the political agenda/s, sometimes directly and sometimes indirectly but either way these days science is affiliated with politics and political decision making - this certainly applies here in Australia. I read in an article something that goes like this: science is the pursuit of knowledge, knowledge is power, and power is politics. Generally the scientific establishment is funded by government which means it is funded by the people but the people do not get much of a say in what research gets to be conducted, this becomes the domain of policy makers and you guessed it the policy makers involved in politics which usually furnish the pockets of companies through products born from scientific research just to condense it a little.
That is just for starters.
