Uh no... cable TV is a good example. It used to be 4-5 OTA channels so everyone watched the same shows.
Now there are like 100's of channels, thats if people even watch cable and aren't off watching netflix, hulu, etc.
As a result everyone has developed very personalized tastes. There are more subgroups of people who think different ways, talk different ways, have different beliefs, etc that are developing far faster than people can even begin to understand them.
Talking like, hipsters, workaholics, work to live, live to work, money is everything, money isn't everything, different ethnicity, nerds, jocks, education levels, etc.
I don't think society has ever been so fragmented.
