What would be news like in a Communism world? time to speculate a bit.
Like, there wouldn't be any wars or class struggle but there still would exist contradictions. Maybe "construction of new solar arrays in [place] causes discussions in Afghanistan" or "Linux OS updates break backwards compatibility. Old-timers create waves of propaganda against updates."
Maybe also celebration of old achievements, like "XXXth Aniversary of Turtle Island liberation", "new library in [rural city] dedicated in the name of deceased comrade educators" etc.
I dunno if there would be any global news. I assume that most contradictions would happen in a local scale; discussed and solved in cadres.
