NPR is a public entity. It's funding, governance, and leadership structure are well known and well trusted. From Wikipedia...

.....Regarding financing;

>Funding for NPR comes from dues and fees paid by member stations, underwriting from corporate sponsors, and annual grants from the publicly funded Corporation for Public Broadcasting.[4] Most of its member stations are owned by non-profit organizations, including public school districts, colleges, and universities. NPR operates independently of any government or corporation, and has full control of its content.[5]

.....Regarding governance;

> NPR is a membership organization. Member stations are required to be non-commercial or non-commercial educational radio stations; have at least five full-time professional employees; operate for at least 18 hours per day; and not be designed solely to further a religious broadcasting philosophy or be used for classroom distance learning programming. Each member station receives one vote at the annual NPR board meetings—exercised by its designated Authorized Station Representative ("A-Rep").

Now, I do question the authenticity of your question. Everyone knows that NPR is reputable and everyone knows why. Their reputation precedes them. But I entertained your charade and now I implore you to entertain one of mine.

Can you provide me the same detailed information which demonstrates why someone should trust OAN? How about Breitbart? How about Newsmax? Can you please pick one and demonstrate why they are trustworthy using a similar format that I provided for you?
