I was wondering this as well because...pokemon came along...when? After my time, anyway, like late 90s.
And then kind of died down, I think, or at least wasn't a monstrous craze at least.
And now in 2016, does it mean that everyone who was super into them 15 years ago is all for it?
If I think about what I was super into at 10, the nostalgia doesn't go that far today.
I mean I see I'm late to the party here and everyone's already said it's real, but I was just surprised.
Around 2007, for some months there, the world was saturated with articles about Second Life. Eventually I saw an article about how it had come about as a result of hiring a new PR firm.
(Or has nostalgia changed? At least if I imagine giving 1940s kids something connected to that in 1965, it seems like they'd be like "Um, I'm a grown wo/man." But today hollyworld is all superhero movies.)
Bonus question: How long before we grow really sick of hearing about it?
