For the past 5 years at least, all young people are computer people. Only some are geeks, but they are all immersed in computerized communications every day.

It's probably not the same, but it's the closest thing we've got.

It's the closest we've got because culture at large is much more heterogeneous than it was 50 years ago. In the 60's, you had 3 channels on TV and had to go to a physical record store to buy music.

Even Justin Bieber is probably bigger and more known than internet memes.

That's not the same generation of consumers though. About a decade or so apart in age I reckon.

I bet hippies weren't too big or popular with the 12 year old crowd either when they were at their peak.

And BTW, Justin Bieber IS an internet meme. He was made famous through a youtube video clip that got him the attention of big producers, a contract and eventually "real" fame.
