That's what I found fascinating about the AJ Liebling angle I mentioned.
He was writing example upon example of how the newspaper consolidation in the 50s and 60's was quite clearly a rightward bias toward monopoly and big business. It was!
How far we've reversed in 30 years!
I had never really considered how far right the papers tilted not just too long ago.
My theory, FWIW, is that the inflection point was 1964, the year that Henry Luce turned over his Editor-In-Chief job to Hedley Donovan.
Luce was reasonably conservative, especially compared to the rest of the journalisto types of the day. His publications tended to moderate the rest of the screaming liberals of the day.
Once he went away, there was nothing to prevent the rest of them from coming loose from their moorings and going full Marxist.
