I find it really interesting that millennials are the ones that people are the most concerned about and compare themselves to the most
I think the reason why we see so many comparison/contrast articles that focus on millennials is because it's the first generation that never knew a world without the internet. Prior to that, everybody got their global awareness from TV, radio, newspapers, magazines, church etc.
Millennials get their information differently (maybe not 100% differently, but as a whole they don't appear to be nearly as focused on legacy media), and it is interesting to analyze the many ways that pans out.
