The idea that "the biased press" is a new and recent thing, as many people believe, and that once upon a time the press was "unbiased" is ridiculous. Eighty years ago the journalist/critic George Seldes, after careful study, concluded that there wasn't a single truly honest newspaper in the United States. *All* of them were held in thrall to advertising and the corporate interests behind that advertising, and only the ad-free New York PM and the tightly-controlled Christian Science Monitor, in his view, came even close to an honest, factual presentation of the news.
The media today is every bit as corporate controlled as it ever was. That's the real bias, not the petty squabbling of political parties over which corrupt crypto-fascist oligarch is going to run the country.
