Having everybody connected leads to homogenization of culture in some ways

The internet may hypothetically homogenize culture relative to a society that does not have any kind of mass communication at all, but relative to the world it was actually introduced into, the internet has completely balkanised the culture. Prior to the internet, we had television, cinema, literature, radio, and newspapers, which were all centralised and controlled enough that they created a shared monoculture in nations. A signifant portion of a country's population would watch, read, and listen to the same media. The internet bucked that trend, allowing all kinds of new subcultures to pop up and to more easily cross national boundaries.
