Honest, balanced reporting; end to political posturing disguised as "news" and commentary based  on fair analysis rather than re-issue of party talking points memos.  
Hard to get "journalists"  to live by such rules but not impossible.  
Subscriptions, both digital and print, might just ramp up again and advertisers feel they were not "taking sides" by buying space.  Quite a challenge and sure to face serious opposition but do to less is to fail.
