>Yes, but the partisanship is likely getting worse, because we each individually get the exact information that is "relevant" to us and therefore feeds our confirmation bias. It's a different form of tribalism from 1950s mass media partisanship. There's actually research (James Hamilton @ Stanford) that shows when capital costs for printing presses were higher, newspapers became less partisan because you had to appeal to everyone to be profitable. The internet, cable news, are helping to unwind that period. I definitely think it's true that mass media has become more partisan. But, as you note, it's not coming from social media. It's coming from the cost of delivering content being driven to practically zero while simultaneously being able to reach nearly everyone in the world.
