I would call the board's attention to some of the newspapers from American history.
The Sally Hemings libel was in a partisan newspaper, the story given by a frustrated man seeking federal employment.
In 1860 (a period with which I am familiar), the Chicago Democrat was a rabidly Republican newspaper. The Jacksonville (Ala.) Republican was just as rabidly pro-Democratic. Richmond has a Douglas Democrat paper (Richmond Dispatch), a Breckinridge Democrat paper (Richmond Enquirer) and a Constitutional Union paper (Richmond Whig). Everybody knew what they were getting when they bought each one.
Partisan press has existed throughout the vast majority of the history of these United States. The aberration was the Progressive Era (say, 1900-1952), when (in theory) "experts" were to be trusted for their objectivity. I would challenge even that period. The range of acceptable opinion was from Truman Democrat to FDR Democrat. Anything outside that range was beyond the Pale. I think the 1960s (Vietnam and Watergate) broke that.
The internet has dramatically changed the system. I hesitate to say it "democratized" the media landscape but it has certainly broadened participation. Look at what media personalities do when they get fired from MSNBC, Fox, CNN, etc. (e.g. Chris Cuomo, Megan Kelly, Brian Stelter, Bill O'Reilly, (Keith Olbermann) They go to the internet.
I do not think the toothpaste is going back in the tube.
