Going back to the 1940s (20s, even), I could articulate to you a sense of each decade in terms of the sound of popular music, the clothing and hair styles, even a color palette associated with that decade.
Right up through the 1990s, I can do that.
But what do the 00s look like? And what distinguishes the 00s and the 10s from each other?
NOT talking about politics or events here, just fashion, music, pop culture, the "look/feel/sound" of the times.
I guess the "hipster" was kind of the persona but it just seems to have less character than times past.
