This level of uniformity cannot come about naturally.

Thomas Schelling says otherwise. See http://nifty.stanford.edu/2014/mccown-schelling-model-segreg... and consider the idea of voluntarty ideological segregation in a virtual space.

I haven't seen that before thanks. I believe what it's showing is why echo chambers form or for that matter why people of similar nationality tend to live in the same neighbourhoods.

Not necessarily that all the major news agencies all push the same story and never question or challenge anything. Or for that matter only challenge the reverse.
