On this page are listed - in no special order - a number of organizations that are worth a look in terms of trying to navigate the world of media bias. Some might lean more toward news, others more toward opinion, and still others that serve as media watchdogs. 

buyer beware

The Sinclair Broadcast Group owns or operates about 123 local broadcasting stations across the country,* covering about 40% of American households. The group has been criticized by some, applauded by others, for its conservative slant to reporting, and apparent requirements that local stations air certain conservative segments. The company is currently awaiting FCC approval to purchase additional stations around the country, which by some accounts would give it coverage of about 70% of American households. How free is our press if they are required to promote a particular piece of propaganda?

* Wikipedia is a reference source I usually take with a grain of salt. But I did find this list interesting - and convenient. You can always verify ownership of your local station if it occurs on this list.

Sinclair has been putting right-wing or pro-Trump flourishes on local news. Two Sinclair honchos, Mark Hyman and Boris Epshteyn, star in conservative video commentary segments that are distributed to TV stations on a “must-air” basis.

Snopes has been fact checking and researching urban legends since 1994. According to their website, "neither the site nor its operators has ever received monies from (or been engaged in any business or editorial relationship with), any sponsor, political party, religious group, outside business organization, or government agency" that is not disclosed on this link

Note: Snopes survives, in part, on advertising money. That doesn't necessarily mean you should believe any of the ads or promotions on their site.

Media Bias/Fact Check (MBFC News) is dedicated to educating the public on media bias and deceptive news practices. MBFC News’ aim is to inspire action and a rejection of overtly biased media. We want to return to an era of straight forward news reporting. MBFC News is considered an independent news outlet, with funding coming from site advertising, individual donors, and "the pockets of our bias checkers."

MBFC allows you to check the bias of other media sources, hopefully allowing you to determine for yourself whether a "news" story can be believed - or how much.
