Maybe I wasn't paying attention?

Because I don't remember ever being discussed besides that one year when Nirvana had the #1 album. And that wasn't this decade.

Generation X is now, mercifully, no longer discussed, possibly because its members are too old to be of interest, and Generations Y and Z passed without much notice because no one ever had a clue who those phrases referred to. In fact, since 9/11 and the recession, the media have generally abandoned their attempts to name and define generational traits, possibly because everybody in the western world appears to be in the same economic and cultural boat.
