The media is already in major splinter mode. Also, John Ziegler makes a great point on his blog that a splintered and diversified media might not work in conservatives' favor.
We conservatives were primarily listening to Rush, Foxnews, etc. and drank the Kool-Aid. We got to hear what we wanted to hear and the liberals got to hear what they wanted to hear on CNN.
Meanwhile the vast majority of Americans are watching Entertainment Tonight and Honey Boo-Boo, and the "capitalists" (liberal or conservative or more likely amoral and apolitical) that own the media corporations are just trying to make a profit and don't care what ways the political winds blow. They will adapt their message to continue to generate profits at the expense of family values, constitutional government, and principled conservatism.
I don’t think the media is all that splintered anymore. The common wisdom had been that the Internet would somehow diminish the influence of Big Media—which has been true but only somewhat. Plus Big Media has finally adapted to emergent realities of the Internet age anyway. And realistically I think there’s only so much the internet can do at this point—i.e., Conservative blog publishers are largely limited to writing derivative editorials of stories put out by Fox News and other major figures…
If Conservatives weren’t locked into Fox News so much (not that they can be particularly faulted for this—Fox News is really the only TV option available for Conservatives and it ain’t all that great), perhaps the echo chamber effect of inter-mutually reinforcing groupthink wouldn’t have been so all-encompassing into bunker mentality as it was.
So having more media POVs available to discern events and information would’ve been useful for purposes of percolating contradictory information about what was really going on in order to erode ossified perceptions. But there just aren’t many frontline news sources for Conservatives outside of Fox News, so this issue will be intransigent.
So long as Conservatives remain exasperatingly limited in media venues for getting the message and the facts out, they will at a distinct disadvantage, relegated to staring extinction in the face in the war of ideas. Ignoring this is suicide.
