> You'll have no problem finding countless examples of weird things that have been viewed and interacted with by hundreds of thousands or even millions of people. I don't think how widespread a piece of media is has a strong correlation with its impact. Yes, several billion people probably know who Grumpy Cat is. But it doesn't matter. Our awareness of Grumpy Cat doesn't change how we think about the world, how we live, how we relate to others. It's just a shared but otherwise mostly meaningless experience, like seeing a rainbow.
The Beat Generation was a relatively tiny subculture whose work at the time was consumed by a small number of people. But we remember them because the work they created mattered. It said something meaningful about the culture it was a reaction to and by doing that, it forced that culture to change.
Beats, hippies, punks, maybe early hackers were all countercultures because they in some way bent the arrow of history. There are no shortage of subcultures today, and they are great for finding people you share interests. But they don't have the same impact as a real counterculture.
