You're never heard of biased or militant journalists have you?

In fact the most common form of journalism you will find is what's akin to a Propaganda channel of a Sponsoring Party (Defense, Media Company, Political party, Rich Individual with an agenda, etc). Essentialy a PR employee.

But this is true since always.

The kind of journalism we usually think of though is Investigative journalism, but that's a different beast and usually doesn't really pay.
