People forget that "yellow journalism" was the baseline, not the exception.
I think much of the argument over bias could be settled by "journalists" having to disclose their political contributions and voting record for the last N years. When people see that a person contributes time, money, and effort to a particular candidate, glowing reviews of that candidate can be taken with a grain of salt.
Personal political contributions (in the US) are mostly on the record, for everyone.
For voting, I don't really see how you do it officially (what do they get in return for their votes being published), so you just reward liars and punish truth tellers.
