How would you translate "新聞の民主性"?


I'm working on a paper about media science and in one of the Japanese papers
the author talks about "新聞の民主性". I do know the general meaning of the word,
but I struggle to put it into proper English or struggle to find the
corresponding English term.

Here's is one of the sentences for context:

井口の新聞学では、彼はマス・コミュニケーションの一つとして相対化され、同時に「新聞の民主性」というイデオロギーが成立した。




........ 「新聞の民主性」というイデオロギーが成立した。

........ and established the ideology of "democratic nature of newspapers."

........ and led to the ideology of "newspapers as a democratizing force."

[code]

             イデオロギー could be idealism, philosophy, notion, ... depending on context.
    
[/code]
