I have also thought about this. We use to have limited tv channels and limited radio stations. On any given day, there was a greater possibility that you shared an experience with your work colleague, your neighbor, or even a stranger. We shared more common culture. Not that I'm pining for "the good ol' days". The internet has facilitated access to a flood of content. I have found great music that would never have been played on the radio. I also realize that no one else in my physical vicinity has or will listen to my favored musicians. Same for tv shows. I think the last common culture most people shared was Game of Thrones. I do think this makes us more isolated from each other.
