Pew Research put out a very good analysis of polling data on political polarization and media habits up to 2014 [1]. It generally finds the same top in WSJ, BBC, NPR, and PBS. Incidentally, I really enjoy looking at the different results you can find in the Pew studies, they are well written and have great figures.
